Question

A yogurt with 1 topping is sold for $3.65. Additional toppings can be added for $0.45 cents each. If y represents the total cost and x represents the total number of toppings added, which function rule describes this pattern? A. y=0.45x+3.65 B. y=3.65+0.45(x-1) C.y=3.65+0.45(x+1) D.3.65(x-1)+0.45

Answer 1

since the 3.65 price includes 1 topping when you calculate the cost of the additional toppings it would be x-1

 so the equation would be y=3.65 +0.45(x-1)
