Question

Cooper is measuring ingredients for his special dessert. He needs a total of 70.4 mL of milk and melted butter. The recipe calls for 30.6 mL of butter. How much milk, m, does Cooper need for his recipe?

Answer 1

milk (m) , butter (b)

m + b = 70.4
b = 30.6

m + 30.6 = 70.4
m = 70.4 - 30.6
m = 39.8 mL of milk are needed
