Answer:
$60
Step-by-step explanation:
2 T-shirts = $15
Longer version
15/2 = $7.50
1 T- shirt = $7.50
7.50*8 = $60
Short version
bought 8 so 8/2 = 4
4*15= 60
x = 7
12x - 16 = 68
Add 16 to each side
12x - 16+16 = 68+16
12x =84
Divide by 12
12x/12 = 84/12
The answer is no 1:
3/5
7/15 + 2/15 = 9/15
both 9 nad 15 are divisible by 3
9/15 = 3/5
