Answer:

Q#1: 1/2 mile

Q#2: 70%

Step-by-step explanation:

Q#1: I set up the proportion below:

[tex]\frac{7}{3.5} = \frac{x}{0.25}[/tex]

Then, I cross-mutiplied to get [tex]3.5x = 7(0.25)[/tex], 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:

[tex]196 = \frac{x}{100} * 280[/tex] and then I solved to get 70%
