A car rental costs $50 for the first day. Additional days cost $35 per day, unless the car is rented for 7 days or more, in whic

son4ous [18]

Answer:

$\$50+\$31.5x$

Step-by-step explanation:

Let

x------> the number of days

y----> the cost of renting a car

we know that

For $x$

$y=\$50+\$35x$

For $x\geq 7\ days$

The rate is equal to

$0.90*\$35=\$31.5$

$y=\$50+\$31.5x$

In this problem. the car has been rented for more than a week

therefore

$x> 7\ days$

The cost of renting a car is equal to

$y=\$50+\$31.5x$
