Jim and Abby each bought burgers and fries from the concession stand at the fair. Jim bought 3 burgers and 2 orders of fries for
$17. Abby bought 2 burgers and 4 orders of fries for $18.
Based on the information above, how much did the concession
stand charge for each burger?
How much did it charge for each order of fries?
HINT:
b = price for a burger
f = price for french fries
Jim bought 3 burgers and 2 orders of fries for $17.
B = price for a burger
F= price for fries
Jim equals 3b + 2f = $17
Abby equals 2b + 4f = $18
Multiply the first equation by -2 & use the elimination to solve
I need would really appreciate if whomever helps me to show the steps. Thank you.

Answer:
Step-by-step explanation:
3b + 2f = 17
2b + 4f = 18
-6b - 4f = -34
6b + 12f = 54
8f = 20
f = $2.50 fries
3b + 2(2.5) = 17
3b + 5 = 17
3b = 12
b = $4 burger
Answer:
3b + 2f = 17
2b + 4f = 18
-6b - 4f = -34
6b + 12f = 54
8f = 20
f = $2.50 fries
3b + 2(2.5) = 17
3b + 5 = 17
3b = 12
b = $4 burger
