Answer:

Subtract the hours to get 12-3 = 9

Or you could start at 3 PM, and count your way up one hour at a time, until you get to 12 AM. You should count out 9 hours in total.

An alternative is you could note from 3 PM to 3 AM is a span of 12 hours. Take 3 hours away from 3 AM, and you'll rewind the clock back to 12 AM. So 12-3 = 9. :-)

plz brainlist plz ;-)

Given : Function f(x) $\mathsf{= \frac{-2}{3}(x) + 1}$

$\mathsf{\implies f(3) = \frac{-2}{3}(3) + 1}$

$\mathsf{\implies f(3) = (-2 + 1)}$

$\mathsf{\implies f(3) = -1}$

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.

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