Question

Lee is buying roses. If each rose costs $2, which equation does not describe how many roses Lee might buy for $24?

Answer 1

`(a)\ y = 2x`

`(b)\ x= 12`

Explanation:

Given

`rose = \$2`

Solving (a): The equation

Let

y = total amount

x = number of roses

So:

If
`x = 1, y = 2`

If x = x.

`y = 2* x`

`y = 2x`

Solving (a): Number of roses for $24

This implies that

`y = 24`

So:

`y = 2x`

`24 = 2x`

Divide both sides by 2

`12 = x`

`x = 12`
