Q. An ice cream stand uses the expression 2+0.5x to determine the cost (in dollars) of an ice cream cone that has x scoops of ice cream.
Determine Cost Expression: To determine the cost of an ice cream cone with x scoops, we need to use the given expression 2+0.5x. This expression indicates that there is a base cost of 2 dollars and an additional cost of 0.5 dollars for each scoop of ice cream.
Calculate Total Cost: Let's calculate the cost for a specific number of scoops, say x scoops. We plug x into the expression to get the total cost.Cost = 2+0.5x
Verify with Example: To ensure we understand the expression correctly, let's check with a simple example. If x=1 (1 scoop of ice cream), the cost would be:Cost = 2+0.5(1)=2+0.5=2.5 dollars.This seems correct as it follows the given expression.
Final Cost Calculation: Now, we can say that for any number of scoops x, the cost of the ice cream cone will be calculated using the expression 2+0.5x. This is a linear expression and does not require any further simplification.
