Answer:
12.8% decrease
Step-by-step explanation:
if you find the unit rate for the sale, which would be 125 cents divided by 3 cans, equals around 43.6 cents per can. 43.6 cents is an x% decrease of 50 cents, and to find x easily i multiplied by 2. 43.6 x 2=87.2, and 50 x 2 = 100. that means that the sale price is 87.2 % of the original price, which is a 12.8% decrease.
Finding x.
Suzette ran = x
Suzette biked = 4x
7 = x + 4x --) 7 = 5x --) 1.4 = x
Suzette ran for 1.4 hours
Finding y.
Quickest way is to use Suzette biked = 4x and substitute the x for 1.4 to find how much she biked.
4 x 1.4 = 5.6
1.4 + 5.6 = 7 hours the total time exercising
And the mileage adds up to.
5(1.4) + 20(5.6) = 119
