Question

Write an equation and solve

Two times the cost of a burger and fries is $10. If the fries are $1 how much is the burger?

Answer 1

10 divided by 2 minus 1 equals 4

Answer 2

Explanation:

• b = cost of 1 burger
• f = cost of fries
• $1 = the cost of fries

2(b+f) = 10

2b + 2f = 10

2b + 2(1) = 10

2b + 2 = 10

- 2 - 2

2b = 8

/2 /2

b = $4 <== the cost of each burger

Check your answer:

2(b+f) = 10

2(4+1) = 10

8 + 2 = 10

10 = 10

This statement is correct

Hope this helps!
