Option C is your answer.
Add (- 3) + 2 to get - 1 for the exponents. 2^ (-1) is the same as 1 / 2^1 which is 1/2.
3[x + 3(4x - 5)] = 15x - 24
3(x + 12x - 15) = 15x - 24
3(13x - 15) = 15x - 24
39x - 45 = 15x - 24 |add 45 to both sides
39x = 15x + 21 |subtract 15x from both sides
24x = 21 |divide both sides by 24
x = 21/24
x = 7/8

Answer:
The price per t-shirts is $8.5.
Step-by-step explanation:
Let us assume the price per t- shirt = $m
The cost of 75 t-shirts = $637.50
Now, the total cost for 75 t-shirts = 75 x ( cost of 1 t-shirt)
⇒ $637.50 = 75 x ( m)
⇒ m = $637.50 / 75
or, m = 8.5
Hence, the price per t-shirts is $8.5.
