Question

PLEASE HELP ME ON BOTH QUESTIONS!! IT'S OK IF YOU CAN ONLY DO ONE OF THEM!

Answer 1

Q#1: 1/2 mile

Q#2: 70%

Explanation:

Q#1: I set up the proportion below:

`(7)/(3.5) = (x)/(0.25)`

Then, I cross-mutiplied to get
`3.5x = 7(0.25)`, and I divided by 3.5 to get 1/2 mile.

Q#2:

Since we know that 196 is the decreased price, it is safe to say that 196 is x% of 280. So, I set up the following equation:

`196 = (x)/(100) * 280` and then I solved to get 70%
