Answer:
$13.68
Step-by-step explanation:
Assuming they rent for 1 year, the cost is broken down as follows:
Annual renting cost = 22% of 722.98 =
Usage charge = 3.2% of 159.06 =
Thus,
Total annual charge = Annual renting cost + Usage charge = 159.06 + 5.09 =164.15
Monthly rental charge would be 164.15 divided by 12 (12 months in 1 year):
dollars
3(9 - 8x - 4x) + 8(3x + 4) = 11
3(9 - 12x) + 8(3x + 4) = 11
27 - 36x + 24x + 32 = 11
59 - 12x = 11
-12x = 11 - 59
-12x = -48
x = 4
hope this helps, God bless!
