Footlocker in the mall is having a 25% off sale on all tennis shoes. Joe paid $67.50 for his

marta [7]

Answer:

The original price of the shoes was $90.

Step-by-step explanation:

25% off means the price Joe paid for it is 75% of the original price.

Set up an equation:

75/100 = 67.50/x

Cross multiply

75 × x = 100 × 67.50

75x = 6750

x = 90

Check our work:

First solve for 25% off of 90 (our answer).

25% = 0.25

90 × 0.25 = 22.50

Next, subtract the discount from 90.

90 - 22.50 = 67.50

67.50 was what Joe paid so this is correct.

Answer:

310.1

Step-by-step explanation:

Use the distance formula:

$\sqrt{(10-2)^2+(235-(-75))^2}$

Simplify inside the parentheses

$\sqrt{(8)^2+(310)^2}$

Simplify exponents

$\sqrt{64+96,100}$

Simplify by adding

$\sqrt{96,164}$

Simplify

$\sqrt{96,164} =310.1$
