Question

The cost of a small frozen yogurt is $2.50 plus $0.15 per topping. The equation that gives the total cost c of a small frozen yogurt is c = 0.15n + 2.50, where n is the number of toppings. What is the cost of a small frozen yogurt with 3 toppings?

Answer 1

The frozen yogurt itself is $2.50 plus $0.15 per topping, if the customer wants one small yogurt and three toppings, ( 2.50 + 0.15(3) ) 

2.50 + 0.15(3) = c
2.50 + 0.45 
2.50 + 0.45 = $2.95

Answer ; $2.95

Answer 2

frozen yogurt is 2.50 and if you want 3 toppings, well one topping is 0.15 so you do .15 plus .15 plus .15 than add 2.50 to that total. which would end up as 2.95
