The price of the box of 15 stickers is $6. the price of the box of 25 stickers is $8. all prices are without tax, and the price of the boxes is the same.

write an equation which tells the price y for the number of x stickers.

y=0.2x+3

Step-by-step explanation:

Let

x> the number of stickers

y> the price

we have that

For x=15, y=6

and

For x=25, y=8

step 1

Find the slope of the linear equation

m=(8-6)/(25-15)

m=2/10=0.10 $/sticker

step 2

Find the equation of the line into point slope form

The equation of the line is equal to

y-y1=m(x-x1)

we have

m=0.10

point (15,6)

substitute

y-6=0.2(x-15)

y=0.2x-3+6

y=0.2x+3
