ANSWER:

1. 59.40

Step-by-step explanation:

A discount is a reduction of the basic price of a good or a service. It can occur on any stage in the process of production or sale - suppliers can put a commercial discount on material prices, or retailers can put a bright red tag that says 15% OFF! on a piece of clothing.  Discounts are often made to prompt sales of outdated stock, reward customers, attract attention or increase profits in the short term.  Oftentimes, we as customers fall into the trap of impulse buying tempted by a discount percent. However, more often than not we lose money, rather than save when we indulge in shopping by buying unnecessary goods prompted by the promise of a lower price.

Answers

Answer:

2) $25.01    3) $25.98

Step-by-step explanation:

2) 23.6 x 7% = 23.6 x .07 (move the decimal 2 places to the right) 23.6 x .07 = 1.652 but its money so round to $1.65 + 23.36 = $25.01

3) 24 x 8.25 = 24 x .0825 (again to the right twice) 24 x .0825 = 1.98+24 = 25.98

3. $1.98

The first round of a racquetball tournament begins with 148 players. Every round, half of the players lose and are eliminated from the tournament leaving 74 players in the second round. The tournament continues in the same fashion until one player finally wins the tournament. Determine if the scenario describes an arithmetic or a geometric sequence then write the formula for the sequence described.

Answers

Answer:

Notice that 99 players need to be eliminated for there to be declared a winner. Notice also that every match eliminates exactly one person. Therefore, 99 matches are needed to eliminate 99 people and therefore declare a winner. The rest of the information is irrelevant. Therefore, the total number of matches is text divisible by 11.

Step-by-step explanation:

You have 1/2 chance of getting tails

You have 1/4 chance of spinning B

1/2 * 1/4 = 1/8

Answer:

1/8

Step-by-step explanation:

When we're looking for the probability of one event and another event to occur together, we multiply their probabilities. Here, the probability of flipping a tails is 1/2, and the probability of spinning a B is 1/4, so the probability that we flip a tails and spin a B is 1/2 · 1/4 = 1/8.

A pair of boots has an original price of $95. They are on sale for 35 percent off. What number can you multiply $95 by to equal the discounted price of $61.75?
A.0.35
B.0.60
C.0.65
D.0.95

Answers

Answer: C- 0.65

Step-by-step explanation:

Answer:
0.65
Step-by-step explanation:
We are given that,
Original cost of the pair of boots = $95
Also, the boots are 35% off.
Since, the discount is 35% of the total amount.
The remaining amount to be paid = 100 - 35 = 65% of the total amount.
Thus, the discounted price = 65% of the total amount
i.e. The discounted price = 65% × $95 = 0.65 × $95 = $61.75
Hence, we need to multiply 0.65 to $95 to get the discounted price of $61.75.

Mike has 40 baseball cards. Tim has 5 less than half of what Mike has. How many baseball cards does Time have?

Answers

Answer:

Give Branliest PLz

Answer is 15

Step-by-step explanation:

Half of 40 is 20 cause 40/2=20

Five less than 20 is 20-5 which= 15

So ur answer is 15

Answer:

15

Step-by-step explanation:

1. We know that Mike has 40 baseball cards total. We know that Tim has 5 less than half of the cards that Mike has.

2. First, we need to divide 40 (Mike's total amount of baseball cards) by 2 or multiply that by 1/2. That gives us 20 baseball cards.

3. Tim has 5 less than half of Mike's deck (20 baseball cards) so we have to take away 5 more cards. 20 - 5 = 15. Tim has 15 baseball cards.
