Rashid [163]

Answer:

An ice cream cone with 5 scoops cost is, $4.5

Step-by-step explanation:

As per the statement:

An ice cream stand uses the expression $2+0.5x$ to determine the cost of an ice cream cone that has x scoops of ice cream.

⇒ Cost of an ice cream cone C(x) = $2+0.5x$ .....[1]

Given: x = 5 scoops

We have to find the cost of an ice cream cone with 5 scoops cost.

Substitute the given value of x =5 in [1] we have;

C(5) = $2+0.5(5)$

C(5) = $2+0.5 \times 5$ = 2 + 2.5 = $4.5

Therefore, an ice cream cone with 5 scoops cost is, $4.5
