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

$1.75

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.
