Answer:
Cost of each hamburger = $1.50
Step-by-step explanation:
Given:
Cost of 3 hamburger and 4 hotdog = $8.50
Cost of 3 hamburger and 6 hotdog = $10.50
Find:
Cost of each hamburger
Computation:
Cost of each hamburger = h
Cost of each hotdog = d
So,
3h + 4d = 8.50.....EQ1
3h + 6d = 10.50.......EQ2
EQ2 - EQ1
2d = 2
d = 1
3h + 4d = 8.50
3h + 4(1) = 8.50
3h = 4.50
h = 1.50
Cost of each hamburger = $1.50
