For a weekly car rental, a car rental company charges customers a flat fee of $100 plus
zlopas [31]

The way you typed out this sentence was a bit confusing but I think you were saying...

For a weekly car rental, a car rental company charges customers a flat fee of $100 +  and charges 10 cents for every mile traveled. write an equation for the amount of a weekly rental car that travels 15 miles (Please let me know if I am wrong)

The equation would be

10+10 +10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10 = 150 cents

so they would be charging $1.50

Hoped this helped!

Have a great day/night! :)

HELP PLZ!! I AM CONFUSED.
Paraphin [41]

Answer:

$ 0.38

Step-by-step explanation:

128 x 4.8 = 614.4

A 128 ounce jug costs $6.14

64 x 5.1 = 326.4

A 64 ounce jug costs $3.26

Two jugs of 64 onces would be equal to the 128 ounces, so double the cost of the 64 ounce.

$3.26 x 2 = $6.52

Then subtract the difference

$6.52 - $6.14 = $0.38
