Question

A superintendent orders some new laptops for two schools in her district. She receives a bill for $7,500. A. Draw a representation that can show the relationship between the number of laptops and the total cost. B. Use the representation to write an equation that can be used to determine the cost of one laptop.

Answer 1

(A)
`n* \$x=\$7500`

(B)
`\$x=(\$7500)/(n)`

Explanation:

Let the number of laptops ordered be denoted by n.

Let the cost of one laptop be $x.

(A)

The representation that can show the relationship between the number of laptops and the total cost is:

`n* \$x=\$7500`

(B)

Write an equation that can be used to determine the cost of one laptop as follows:

`n* \$x=\$7500`

`\$x=(\$7500)/(n)`
