Answer:
it will take 3 hours
Step-by-step explanation:
mom
packages = 6+ 50 *h
dad
packages = 42 + 38h
set them equal
6+50h = 42 + 38h
subtract 38h from each side
6+50h-38h = 42+38h-38h
6+12h = 42
subtract 6 from each side
6-6+12h = 42-6
12h =36
divide by 12
12h/12 = 36/12
h = 3
it will take 3 hours
