Students sold 390 tickets for a fundraiser at school.
Some tickets are for children and cost $2, while the
rest are adult tickets that cost $5. If the total value of
all tickets sold was $1,470, how many of each type of
ticket was sold?

Answers

Answer 1


a = number of adult tix = 230
c = number of child tix = 160

a + c = 390 for number of tickets sold
5a + 2c = 1470 for money earned

First we’ll solve for c in terms of a
c = 390-a

Then we’ll substitute that expression in to solve for a numerical value for c:

5a + 2c = 1470
5a + 2(390 - a) = 1470
5a + 780 -2a = 1470
3a = 690
a = 230

Then we’ll drop that into the first equation to get a numerical value for c

c = 390 - a
c = 390 - 230
c = 160

Check the math:
5a + 2c = 1470
5(230) + 2(160) =
1150 + 320 = 1470

Maria is shopping for party supplies. She finds that paper plates come in packages of eight, napkins come in packages of 10, and paper cups come in packages of 12, what is the least number of packages of plates napkins and cups she has to buy so that she has the same number of each Item for her birthday party.

Answers

Answer

15 plates, 12 napkins and 10 cups

Step-by-step explanation:

To find the least amount, you have to find the lcm of all three numbers. In this case the lcm of 8,10, and 12 is 120. Afterwards you need to divied 120 by all numbers. So 120 divided by 8 is 15, so 15 plates. 120 divided by 10 is 12, so 12 napkins and finally 120 divided by 12 is 10, so 10 cups

The least number of packages of plates, napkins, and cups Maia has to buy so that she has the same number of each Item for her birthday party is 15, 12, and 10, respectively.

What is a Fraction?

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

Given that paper plates come in packages of eight, napkins come in packages of 10, and paper cups come in packages of 12. Therefore, to find the least number of packages of plates napkins and cups Maria has to buy so that she has the same number of each Item for her birthday party, we need to take the LCM of the following.

LCM of 8, 10, and 12 = 120

Now, the number of packages,

[tex]\text{Number of paper plate packs} = \dfrac{120}{8}=15[/tex]

[tex]\text{Number of napkins pack} = \dfrac{120}{10}=12[/tex]

[tex]\text{Number of paper cups pack} = \dfrac{120}{12}=10[/tex]

Hence, the least number of packages of plates, napkins, and cups Maia has to buy so that she has the same number of each Item for her birthday party is 15, 12, and 10, respectively.

A welder and a carpenter decided to get out of the construction industry and build farm trailers instead. From building a few trailers on weekends, they estimated that the first trailer would take about $700 of their own labor to build and that an 85 percent learning rate can be anticipated on the cumulative average time as each trailer is built. (Note: They decided that their hourly wages should be no less than those they received in the construction trades.) The material costs for each trailer will be about $500, and the craftsmen do not see any way that this can be reduced. They estimate that each trailer can be sold for $1,000. In addition to making their wages on labor, they want to make 15 percent profit on the trailer materials.
