Shelby, Allen, and Denise printed their digital photos. Each requested the same size prints. Shelby paid $2.70 for 5 prints. Allen paid $3.24 for 11 prints. Denise paid $4.05 for 20 prints. Describe how you would write the equation for the relationship between the number of photos ordered and the amount paid.

Respuesta :

Answer:

[tex]y = 0.54x[tex], where [tex]x[tex] is the number of photos printed and [tex]y[tex] is the amount paid.

Step-by-step explanation:

We simply need to get the price to print one photo. Shelby paid $2.70 for 5 photos, so each photo is [tex]2.70 / 5 = $0.54[tex]. So then the equation is 0.54, which is the price, multiplied by [tex]x[tex], which is the number of photos, equal to [tex]y[tex], which is the amount paid.
