The soccer club is selling t-shirts and washing cars to raise money for a summer trip. last week, the club raised $292.50 by selling 15 t-shirts and washing 12 cars. this week, it raised $747.50 by selling 45 t-shirts and washing 10 cars.
(a) write two equations showing the money the club raised each week, where x is the amount earned per t-shirt sold and y is the amount earned per car washed.
(b) how much does the soccer club charge for a t-shirt? show your work.
(c) how much does the soccer club charge for a car wash? show your work.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
