Answer 2

Answer:

Step-by-step explanation:

A) Cost of canvas = $ x

Cost of  4 canvases = 4 *x = 4x

Money left over after buying 4 canvases = $2.20

Equation:  25 - 4x = 2.2

Solution:     Subtract 25 from both sides

                -4x = 2.2 - 25

               -4x = - 22.8

Divide both sides by (-4)

    -4x/-4 = -22.8/-4

              x =  5.7

B) Money in Molly's account= x

4 times of Molly's account  = 4x

Equation: 4x - 2.2 = 25

Solution:   4x = 25 +2.2

                  4x = 27.2

                    x = 27.2/4

                   x = 6.8
