Question

The school store sells binders for $5 and notebooks for $4. The store needs to sell $80 worth of these two items combined each week. Write a linear equation in standard form that describes the linear relationship. Let x represent the number of binders sold and let y represent the number of notebooks sold.

Answer 1

Answer:Your answer is....

Explanation:

80=5x+4y

Answer 2

80=5x+4y

Explanation:

Step one:

given

let binders be x

and notebooks be y

let the total sale be T

the cost of binder is $5 each

the cost of notebook is $4 each.

the total sales expected is $80

step two:

the linear model for the total sales is given as

T=x+y

using the given data, the situation can be represented linearly as

80=5x+4y

Therefore the linear expression for the total sale is 80=5x+4y
