Question

Deborah is going to the movies. Her ticket cost $11.50 and each ofthe snacks are $2.50 each. If she spends a total of $19, how manysnacks did she buy? (Write and solve an equation to represent thissituation.)

Answer 1

3 snacks

Explanations:

Let the number of snacks Deborah bought be "x"

Given the following parameters:

Cost of her ticket = $11.50

Cost of "x" snacks = $2.50x

If the amount she spent in total is $19, the required equation that represents the situation will be expressed as:

2.50x + 11.50 = 19

Subtract 11.50 from both sides

2.50x + 11.50 - 11.50 = 19 - 11.50

2.50x = 19 - 11.50

2.50x = 7.50

Divide both sides by 2.50

2.50x/2.50 = 7.50/2.50

x = 7.50/2.50

x = 3

Therefore the amount of snacks she bought is 3 snacks
