6 adults and 11 children.

In order to solve this problem we going to use linear equations.

A group of 17 people went to the concert. There are adults and children in that group x + y = 17 where x are adults and y are children. That group pay $57.50 for tickets, if tickets cost $5.00 for adults and $2.50 for children, then 5.00x + 2.50y = 57.50.

x + y = 17 ---------->  y = 17 - x

Substituting the value of y in the equation 5.00x + 2.50y = 57.50:

5.00x + 2.50(17 - x) = 57.50 solving

x = 6

Substituting x = 6 in the equation x + y = 17

6 + y = 17 solving

y = 11

From a group of 17 people who went to the concert 6 are adults and 11 are children.

If Jake buys 3 new shirts, how many of them would you expect to be t-shirts, and how many would you expect to be collared?
Sophie [7]

Answer:

2 t-shirts ; 1 collar shirt

Step-by-step explanation:

We need to first obtain the ratio of T - shirts to collar shirts :

T - shirts = 10

Collar shirts = 5

Ratio = T - shirts / Collar shirts = 10 / 5 = 2 /1 = 2:1

Hence, using the ratio obtained ; if Jake buys 3 new shirts :

Number of T-shirts :

(Ratio of t-shirts / total ratio) * new t-shirts

2/3 * 3 = 2 t-shirts

Collar shirts :

1/3 * 3 = 1

2 t-shirts ; 1 collar shirt
