Question

lan spent half his fun money going to the new Avengers movie. He mowed
the neighbor's lawn to 8 more dollars for his fun money. How much fun
money did he have to start with if he ended with eighteen dollars?

Answer 1

Answer:

$20

Step-by-step explanation:

We need to work backwards. If he ended with $18 we can subtract the $8 he gained from mowing the lawn. Before he mowed the lawn he had $10. If he spent half his money on the movie we need to double the funds he had after the movie giving us $20.
