Question

Clare used 20% less oil this month than last month. If she used 155 tablespoons of oil last month, how many tablespoons did she use this month?

Answer 1

124 teaspoons.

Explanation:

Let spoons used this month be denoted by t

According to given condition:

155 - 20% of 155 = t

By simplifying

155 - 0.2(155) = t

155 - 31 = t

124 = t

so the oil used is 124 teaspoons.
