Question

3 packs of soda cost $10 less than 5 packs of soda. write an equation that models this.

Answer 1

Cost 1 pack = x

3x + 10 = 5x;

2x = 10;

x = 5.

1 pack cost $5

Answer 2

For this case, the first thing we must do is define a variable.

We have then:

x: unit cost of each pack of soda

We now write the equation that models the problem.

We know that:

3 packs of soda cost $ 10 less than 5 packs of soda.

We have then:

`image`

Answer:

an equation that models this is:

`3x = 5x - 10`
