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

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

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
