One dollar and eighty-seven cents. That was all. And sixty cents of it was in pennies."

gladu [14]

To model the scenario, the following will be the numerical coefficients for the variables: 0.05 for nickels (5 cents), 0.10 for dime (10 cents) and 0.25 for quaters (25 cents). Thus the model/equation is, $1.87 = 0.25q + 0.10d + 0.05n + 60.

Rachel Perez rented a car for 3 days at $40.00 per day, plus $0.20 per mile. To protect herself in case of an accident, she purc

expeople1 [14]

Answer:

$290.

Step-by-step explanation:

We have been given that Rachel Perez rented a car for 3 days at $40.00 per day.

$\text{The cost of renting a car for 3 days}=3\times \$40$

$\text{The cost of renting a car for 3 days}=\$120$

We are also told that she pays $0.20 per mile for renting the car. As she covered a total distance of 500 miles, so cost of renting car foe 500 miles will be:

$\text{Cost of renting the car for 500 miles}=500\times \$0.20$

$\text{Cost of renting the car for 500 miles}=\$100$

As Rachel purchased the collision deductible for $10.00 per day to protect herself in case of an accident, so cost of collision deductible for 3 days will be:

$\text{The cost of collision deductible for 3 days}=3\times \$10$

$\text{The cost of collision deductible for 3 days}=\$30$

She also paid $40 for gasoline to cover 500 miles, so we can find total cost to rent the car for 3 days to cover 500 miles by adding all the expenses.

$\text{The total cost to rent the car}=\$120+\$100+\$30+\$40$
