The Miller family visited Mama's Kitchen and ordered 4 hamburgers and 3 medium fries and paid $13.44. James ordered a medium drink, a hamburger, and 2 medium fries and paid $5.81. Steven ordered 2 hamburgers, medium fries, and a medium drink for $7.35. How much did each item cost?
divide 13.44 by 4 to get the hamburger cost. then divide 13.44 by 3 to get the fries cost. do the same to the other amount to get a cost for every item
Answer:
Hamburger costs $2.58
Fries costs $1.04
Drink costs $1.15
Step-by-step explanation:
Let hamburgers cost = h
Let fries cost = f
Let drinks cost = d
The Miller family visited Mama's Kitchen and ordered 4 hamburgers and 3 medium fries and paid $13.44.
\(4h+3f=13.44\) ....(1)
James ordered a medium drink, a hamburger, and 2 medium fries and paid $5.81.

Steven ordered 2 hamburgers, medium fries, and a medium drink for $7.35.
\(2h+f+d=7.35\) ....(3)
Subtracting (2) from (3) to eliminate d
\(h-f=1.54\) ....(4)
Now multiplying (4) by 4 and subtracting from (1) to eliminate h
\(7f=7.28\)
f = $1.04

h = $2.58
We know \(h+2f+d=5.81\)
Substituting values of h and f
\(2.58+2(1.04)+d=5.81\)
\(2.58+2.08+d=5.81\)
\(4.66+d=5.81\)
\(d=5.81-4.66=1.15\)
d = $1.15
Therefore, a hamburger costs $2.58
Fries costs $1.04
Drink costs $1.15
