Question

Alejandra paints faces at kids’ birthday parties to earn extra money. The equation

M = 2.50f + 12 represents the relationship between the money she makes, M, and the number of faces she paints, f.
• Alejandra wants to buy a new pair of Uggs that cost $119.50. How many faces does she need to paint

Answer 1

43 faces

--------------------------

Answer 2

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
