Question

a) Choose a variable to represent the price of an ice-cream voucher. Write an equation to model this problem.

b) Solve the equation using the distributive property.

c) Verify the solution. Explain your thinking in words.

Answer 1

Number of friends =5

Cost of meal voucher=$8

Let the cost of an ice-cream voucher be $x

5(8+x)=55

40+5x=55

5x=55-40

5x=15

x=15/5

x=3

The cost of an ice-cream  voucher is $3

check

5(8+3)=5(11)=55
