Answer:

Step-by-step explanation:

m = 2.50f + 12.....m represents the total money she makes

and if she wants to buy the uggs, she needs to make 119.50.....so sub 119.50 in for m and solve for f

119.50 = 2.50f + 12

119.50 - 12 = 2.50f

107.50 = 2.50f

107.50 / 2.50 = f

43 = f <=== she needs to paint 43 faces to get enough money to buy her uggs
