Question

Trevor split his savings of $59.75 equally to buy birthday presents for each of his friends with a birthday in March. If he spent $11.95 on each present, which equation gives the number of Trevor's friends who have a birthday in March?

Answer 1

Let x be the number of friends:

Then 59.75/x =11.95
=> 11.95x = 59.75
=> 11.95x - 59.75 =0
or x = 59.75/11.95 =5

Therfore he has 5 friends.
