Answer 1

(a) C = 0.29t + 2.50

(b) 5

Explanation:

The variables are defined as follows:

t = the number of toppings

C = total cost for ice cream

It is provided that:

• An ice cream with no toppings is $2.50.
• Every topping is priced at $0.29 each.

(a)

The algebraic equation to find the total cost for ice cream depending on the number of toppings is:

C = 0.29t + 2.50

(b)

Compute the number of toppings Mr. Torrance can buy if he wants to spend only $4.00 on it as follows:

C = 0.29t + 2.50

4.00 = 0.29t + 2.50

0.29t = 4.00 - 2.50

0.29t = 1.50

t = 5.1724

t ≈ 5

Thus, Mr. Torrance can buy 5 toppings.
