Question

Alex earned $7 per hour at his job plus an additional $50 in tips on Friday. He earned less than $99 total. Write a solution to determine how many hours Alex worked that Friday.

Answer 1

99-50=49
49÷7=7,
but since he earned LESS than 99,
92-50=42
42÷7=6

Answer 2

He worked 7 hours on Friday, with an additional of $50 thanks to tips.

Explanation:

First, take away the $50.

Second, find how many hours it takes to get $49.

Third, $50 + $49 = $99

Fourth, you've got your answer.
