Answer:
a. $52.20
b. [tex]z=11x+0.09y[/tex]
Step-by-step explanation:
[tex]z=7x+0.11y[/tex]
a.
x = 4
y = 220
[tex]z=(7*4)+(0.11*220)\\z=28+24.2\\z=52.2[/tex]
It costs $52.20 under those conditions.
b.
[tex]z=11x+0.09y[/tex]
If z is still how much it costs in total
If x is how many days rented
If y is how many miles driven
