Question

A yogurt with 1 topping is sold for $3.75. Additional toppings can be added for $0.65 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=3.75(x-1)+0.65
B) y=3.75-0.65(x+1)
C) y=3.75+0.65x
D) y=3.75+0.65(x-1)

And how did you get that answer

Answer 1

C. the initial cost is 3.75 and each aditonal topping is0.65 meaning x is how many mor toppings the person got.

Answer 2

It's D

Since Y is the total whatever the eqaution is it will equal to Y

And since 3.75 is the cost one yogurt with 1 topping we add it by the cost of each topping which is 0.65.

If X equals the number of toppings we minus that by one.
