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.

[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.

wrote the ordered pairs (5, 2.70),  (11, 3.24), and (20, 4.05)

used two of the ordered pairs to find the slope

wrote the point-slope form for a linear equation

substituted the slope and the coordinates of one of the points to write the equation of the line

Step-by-step explanation:

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
