If it takes 15 gallons of gas to drive 330 miles how many miles can be driven using 20 gallon of gas

Iteru [2.4K]

15 / 330 = 20 / x...15 gal. to 330 miles = 20 gal to x miles
cross multiply because this is a proportion
(15)(x) = (20)(330)
15x = 6600
x = 6600/15
x = 440 <=== 20 gallons will take u 440 miles

The original price of a toaster is $18.00. If the toaster is marked down 25%, what is the new price?

Alla [95]

Answer:

$13.50

Step-by-step explanation:

First, we got to multiply $18 by 25% or .25

$18 x .25 = $4.50

Lastly, we just subtract $4.50 from $18.

$18 - $4.50 = $13.50
