Question

Eric earns $7.50 per hour working at a grocery store. Every day he makes about $10 in tips for helping customers carry groceries to the car. The total amount of money he earns on a given day is a function of how many hours he works that day. If he typically works between 1 and 5 hours each day, which is the reasonable range for this function?

Answer 1

The reasonable range for Eric's daily earnings at the grocery store, where he earns $7.50 per hour and about $10 in tips, is $17.50 to $47.50, based on working 1 to 5 hours a day.

Step-by-step explanation:

The question is asking to define the reasonable range for the function that represents Eric's total daily earnings from working at a grocery store, where he earns $7.50 per hour plus tips. Eric typically works between 1 and 5 hours each day and makes about $10 in tips each day. To calculate the range of earnings, we multiply the number of hours by $7.50 and then add $10 for tips.

For 1 hour of work, Eric earns $7.50 * 1 hour + $10 = $17.50.
For 5 hours of work, Eric earns $7.50 * 5 hours + $10 = $47.50.

Thus, the reasonable range for the total amount of money Eric earns in a day is $17.50 to $47.50, depending on the number of hours he works.
