Question

Last week Dan had 41 dollars and Keith had 23 dollars. Dan washed cars over the weekend and now has 78 dollars. How much money did Dan make washing cars? Which equation best fits this situation?

Answer 1

Answer:

Dan made $37 washing cars

equation: 41 + n = 78

Step-by-step explanation:

41 + n = 78

to solve, subtract 41 on both sides of the equation:

41 - 41 + n = 78 - 41

n = 37
