So then Mark purchased 12 Hamburgers and 6 packages of buns
Step-by-step explanation:
For this case we can define the following notation:
B represent the number of packages buns
H represent the number of hamburgers
And from the information given we can set up the conditions into the following equations:
(1) represent the total cost
(2) represent the total number of items
Solving H from equation (2) we got:
(3)
And replacing equation (3) into equation (1) we got:
And dsitributing the terms we have:
And solving for B we got:
And dividing by 5.25 we got:
And replacing the value of B into equation (3) we got:
So then Mark purchased 12 Hamburgers and 6 packages of buns
