2) a construction contractor used the equation 11.52=(1.44)8 to
calculate how much 8 boxes of nails would cost him. how
much would 2 boxes of nails cost him?

2.88

Explanation:

If you break down the equation we see that 8 is the number of boxes and 1.44 is the price of each box. So if you wanted to change the equation the formula would be: (1.44)x = cost so if you wanted to figure out how much 2 boxes would be, you just plug in 2 for x and you get (1.44)2 = 2.88
