Answer: 42.50
Step-by-step explanation: sale price is the price at which something sells or is sold at after its price has been reduced
75 + 25 x = 30 + 40 x
x = 3
If you rent them for 3 hours they have the same payment of 150
A(x) = 3x - 12
b(x) = x - 9
a(b(x)) = a(x - 9) = 3(x - 9) - 12 = 3x - 27 - 12 = 3x - 39
a(b(x)) = 3x - 39
You have $ 16 + $ 5 = $ 21 in value
$ 21 / $ 7 = 3 bottles, excluding tax<span> </span>
