Respuesta :

Jennifer works at McDonalds, and she can make 36 burgers an hour. Let h = hour. Let J = Jennifer's total

J = 36h

David, on the other hands, works at Burger King, and he makes 12 burgers an hour. Let D = David's total

D = 12h

-----------------------------------------------------------------------------------------------------------------

This time, however, Jennifer only works 2 hours. Plug in 2 for h

J = 36h; J = 36(2);

Simplify

36 x 2= 72

Jennifer makes 72 burgers in 2 hours

------------------------------------------------------------------------------------------------------------------

David, on the other hand:

12 burgers an hour. Divide 72 with 12

72/12 = 6

David needs 6 hours to make 72 burgers

------------------------------------------------------------------------------------------------------------------

Check: 6 hours x 12 burgers per hour = 72 total.

           2 hours x 36 burgers per hour = 72 total.

hope this helps
