Question

Solve the word problem. Tom plans to mow a lawn today to earn some extra money. He estimates that he will spend $1.80 on fuel and $3.45 on lunch. He will charge $11.50 to mow the lawn. What will be his profit for mowing the lawn?
a. $5.25
b. $6.25
c. $9.85
d. $16.75

Answer 1

b. $6.25 because you have to add the money he spent and subtract it from the money he charges for the lawn. :3

Answer 2

Subtract  the $5.25 spent on the fuel and lunch from the $11.50 he charged. 

$11.50
   -5.25           ($1.80 +$3.45) = $5.25 spent
=$6.25
