Michael wants to purchase a jeep. The purchase price of the Jeep is $37,000. The
dealership will allow him to pay cash or finance the Jeep with a down payment of
$5,000.00 and 60 monthly payments of $625.00. Michael chose to finance the jeep.
Answer the following questions.
a) What is the amount financed?
b) What is the total amount of monthly payments?
C} What is the amount of the finance charge?

Answers

Answer:

A) $32,000 B) $37,500 C) $5,500

Step-by-step explanation:

Price of jeep: $37,000

Michael uses $5,000 of his own money toward that total $37,000-$5,000= $32,000

Monthly payments $625.00×60months=$37,500

After paying $5,000 of his own money, & bringing theamount owed to $32,000. Michael still has to pay back $37,500. Making, the finance chardge $5,500. ($37,500-$32,000= $5,500)

Amount financed =  $32000, total amount of monthly payment = $37500 and total amount of the finance charge = $5500.

What is dealership finance ?

"Dealer financing is a type of loan that is originated by a retailer to its customers and then sold to a bank or other third-party financial institution. The bank purchases these loans at a discount and then collects principle and interest payments from the borrower. This is also called an indirect loan."

According to the question,

Given,

Price of jeep = $37000

Down payment = $5000

Total number of monthly payment = 60

Amount to be paid after down payment

= $37000 - $5000

= $32000                                                  ____( 1 )

Amount paid in Monthly payments = $625.00 × 60months

                                                          = $37500          ____( 2 )

From ( 1 ) and ( 2 ) we get,

Finance charge amount = Total monthly amount - Total amount financed

                                        = $37500 - $32000                                    

                                        = $5500

Hence, amount financed , total amount monthly payment and total amount of the finance charge is $32000 , $37500 and $5500.

Answer:

x=59

Step-by-step explanation:

The sum of the interior angles of a triangle add up to 180 degrees.  That means that (x+12)+(x)+(x-9)=180 degrees in total.  If we combine the like terms (combine the xs and regular constant values), the xs add up to 3x (x+x+x) and the regular constants add up to 3 (12+-9=3).  If we rewrite this in a more simplified form, we get 3x+3=180.  Subtract 3 on both sides to get 3x=177 because we want to isolate x.  3x=177 divide 3 on both sides and we get 59.  x=59

Given is that a baby is 18in long at birth and 27in long in ten months

At birth, the length of baby = 18 inches.

After 10 months, the length of the baby = 27 inches.

Increase in length per month will be -

r = (27 - 18)/(10 - 0)

r = 9/10

r = 0.9 inch

Therefore, the length of the baby will increase 0.9 inch per month.

Answers

Answer:

what is

Step-by-step explanation:

The sample proportion of the teenagers 13 to 17 years of age who use social media​ is 0.236.

What is a Sample Proportion?

Sample proportion is defined as the proportion of something from a given sample which has a particular characteristic.

The formula to calculate the sample proportion is,

p = Number of successes in a particular sample / Sample size

Given that,

a random sample of n = 330 teenagers 13 to 17 years of age was asked if they use social media.

Sample size = 330

Of those surveyed, 252 stated that they do use social media.

We have to find the proportion of teenagers 13 to 17 years of age who use social media​.

Number of failures = 252

Number of successes = 330 - 252 = 78

Sample proportion = 78 / 330 = 0.236

Hence the sample proportion is 0.236.

Finally somebody asked whatthe problem was, and Lemon looked down at his hands and said that back in high school he'd had a couple of badexperiences with dentists. Real sadism, he said. Torture chamber stuff. He didn't mind blood or pain - he actually enjoyedcombat - but there was something about a dentist that just gave him the creeps. He glanced over at the field tent and said,"No way. Count me out. Nobody messes with these teeth.But a few minutes later, when the dentist called his name. Lemon stood up and walked into the tent.It was over fast. He fainted even before the man touched him.Four of us had to hoist him up and lay him on the cot. When he came to, there was a funny new look on his face, almostsheepish, as if he'd been caught committing some terrible crime. He wouldn't talk to anyone. For the rest of the day hestayed off by himself, sitting alone under a tree, just staring down at the field tent. He seemed a little dazed. Now and then wecould hear him cussing, bawling himself out. Anyone else would ve laughed it off, but for Curt Lemon it was too much. Theembarrassment must've turned a screw in his head. Late that night he crept down to the dental tent. He switched on aflashlight, woke up the young captain, and told him he had a monster toothache. A killer, he said - like a nail in his jaw. Thedentist couldn't find any problem, but Lemon kept insisting, so the man finally shrugged and shot in the Novocain and yankedout a perfectly good tooth. There was some pain, no doubt, but in the morning Curt Lemon was all smiles. By the end, Curt Lemon is characterized as: 1)Recklessly concerned with his reputation. 2)battle-hardened and powerful. 3)Overly impulsive but cheerful. 4)Childish and prone to fainting.
