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

\text{The total cost to rent the car}=\$290

Therefore, the total cost to rent the car was $290.

Nine years ago, Kimo was twice as old as Jennifer was then. In four years, Jennifer will be the same age that Kimo is now? How o
Georgia [21]

Answer:Kimo is 17 years old and Jennifer is 13 years old.

Step-by-step explanation:

Let x represent Kimo's current age.

Let y represent Jennifer's current age.

Nine years ago, Kimo was twice as old as Jennifer was then. It means that

x - 9 = 2(y - 9)

x - 9 = 2y - 18

x = 2y - 18 + 9 = 2y - 9

In four years, Jennifer will be the same age that Kimo is now. It means that

x = y + 4 - - - - - - - - - 1

Substituting x = 2y - 9 into equation 1, it becomes

2y - 9 = y + 4

2y - y = 4 + 9

y = 13

x = 2y - 9 = 2 × 13 - 9

x = 17
