A bar chart shows monthly rainfall: Jan 80mm, Feb 60mm, Mar 100mm, Apr 40mm. What is the average monthly rainfall over these four months?

Accepted Answer

70mm

Answer

Average = (80 + 60 + 100 + 40) / 4 = 280 / 4 = 70mm.

Question 2

A store sells a jacket for $120 after applying a 25% discount. What was the original price?

Accepted Answer

$160

Answer

The sale price is 75% of the original, so original = $120 / 0.75 = $160.
