Two customers go to a fast food restaurant the first customer buys two burgers and one french fry for $4.75 the second customer
buys three hamburgers and three french fries for nine dollars how much does each hamburger cost
1 answer:
Answer: $1.75
Step-by-step explanation:
Assume hamburgers are x and French fries are y.
Use a simultaneous equation to solve;
2x + y = 4.75
3x + 3y = 9.00
Using substitution;
2x + y = 4.75
y = 4.75 - 2x
Solving it;
3x + 3y = 9
3x + 3 * (4.75 - 2x) = 9
3x + 14.25 - 6x = 9
-3x = 9 - 14.25
-3x = -5.25
x= -5.25/-3
x = 1.75
y = 4.75 - 2x
= 4.75 - 2 * 1.75
= 1.25
Hamburgers are x so they cost $1.75 each.
