Answer:
54.91
Step-by-step explanation:
64.6/x=100/85
(64.6/x)*x=(100/85)*x
64.6=1.17*x (divide both sides of the equation by 1.17 to get x)
54.91=x
x=54.91
now we have 85% of 64.6= 54.91
Answer:
the correct answer is option D
Answer:
For this problem we can use the following proportional rule:

Where x represent the number of miles that we can travel with 75 gallons. For this case we can use this proportional rule since by definition
. If we solve for x we got:

And the best answer would be:
219 mi
