Question

Select the letter of the correct answer.

Answer 1

First we have to find how much gas was used:
We divide 3.3 by 129 to see how many 3.3 is in 129 (if that make sense)
However, we will get 39.09
Since one gallon is 3.3 miles then 39.09 gallons of gas was used.
So how much is now left we minus 180-39.09 = 140.91
We now find what percentage is 140.91 of 180.
n/100 × 180 = 140.91
n/100 = 140.91/180
n/100 =
n = 0.7828*100
n = 78.28

There n is equal to 78 % to the nearest percent

Answer 2

Would it be B which is 51%
as you do 129 devided by 3.3 = 39.1
180-39.1= 141
141 is just over half
