Answer: Each burger costs $4 and each order of fries costs $2.5 .
Step-by-step explanation:
Let x be the cost of each burger and y be the cost of each orders of fries.
Given : Jim bought 3 burgers and 2 orders of fries for $17.
Abby bought 2 burgers and 4 orders of fries for $18.
Then, the system of linear equation will become :
Divide by 2 on each sides of equation (2), we get
Eliminate equation (3) from (1), we get
Divide by 2 on both sides , we get
x=4
Put value of x in (3), we get
Subtract 3 both sides, we gte
Divide by 2 both sides , we get
y=2.5
Hence, each burger costs $4 and each order of fries costs $2.5 .
