Mom has only wrapped 6 packages, but she can wrap 50 packages per hour. Dad has already wrapped 42 packages, but he can only 38 packages per hour. How many hours will it take for Mom to have wrapped as many packages as Dad?

Respuesta :

write them as equations
y=50x+6
y=38x+42
then solve
50x+6=38x+42
12x=36
x=3
so three hours.
