Question

Shandra scored 75 on her first math test. She scored

20% higher on her next math test. What did she score
on her second test?

Answer 1

She scored 90 on her second math test.

Explanation:

A 20% increase is 120% of the original number. 120% is also just a multiplier of 1.2. Multiply the first score by 1.2 to get the second score:

`75*1.2=90`

She scored 90 on her second math test.

Answer 2

90

Explanation:

20% of 75 is 7.5 times 2 which equals 15 so 15 plus 75 is 90.
