Bella started her own business. One weekend she sold 3 regular and 9 fluffy slimes for $84. The next weekend she sold 4 regular and 2 fluffy slimes for $53.50. How much does she sell each type of slime for?

$5.85 = cost for fluffy slime

4r + 2(5.85) = 53.5

Step-by-step explanation:

Let r = cost of regular

     f = cost of fluffy

(1)    3r + 9f = 84              (2)    4r + 2f = 53.5

4 x (1)      12r + 36f =  336

-3 x (2) -12r - 6f =  -160.5

                     30f = 175.5

                         f = $5.85 = cost for fluffy slime

4r + 2(5.85) = 53.5

4r + 11.7 = 53.5

4r = 41.8

r = $10.45 = cost for regular
