Answer 1

Answer:

$10.13

Step-by-step explanation:

Given the rent fee is $6.50 plus $2.25/hr proportionally charged on hours used.

#We calculate bills total expenses after 1 1/2 hrs:

$Total=Fixed +Variable cost\\\\=6.50+2.25\times1\frac{1}{2}\\\\=9.875$

#Subtract bills total expense from the amount he gives to determine the balance amount:

$Balance=Amount- Expenses\\\\=20-9.875\\\\=10.125\approx10.13$

Hence, Brent's change is $10.13
