You order 4 hamburgers and a chicken sandwich. The cost of the chicken sandwich is $2.50. Your total bill before
tax is $12.30. Write and solve an equation to find the cost of a hamburger.

Respuesta :

Answer:

A hamburger costs $2.45.

Step-by-step explanation:

Use this equation 4x + 2.50 = 12.30

Subtract 2.50 on both sides of the equation.  4x = 9.80

Then divide to get x by itself.  X = 2.45

X represents the price of one hamburger.
