Answer 1

$105.00

Explanation:

Greg's Dad pays him $50 plus $5 for each car he washes. He washed 11 cars, so he made 11×$5. 11×5 is 55 (Any single digit number multiplied by 11 is just two of that number side by side: 11×6=66, 11×4=44, etc.) So, if you add $55 to the $50 his dad gave him originally, you get $105. Greg made $105.00 on Saturday. I wish I could be so lucky!!
