Question

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. A Write an equation which tells the price Y for the number of X stickers.

Answer 1

Answer:

$y=0.2x+3$

Step-by-step explanation:

Let

x ----> the number of stickers

y ----> the price of the boxes

we have the points

$A(15,6),B(25,8)$

Find the slope

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

$m=2/10=0.20$

Find the equation of the line into point slope form

The equation is equal to

$y-y1=m(x-x1)$

substitute the value of m and the point A

$y-6=0.2(x-15)$

$y=0.2x-3+6$

$y=0.2x+3$ ----> linear equation that represent the situation
