Final answer:
The expression 14.97n + 29 represents the total spending by Gabe at a store based on the number of items he buys, where 'n' is the number of items.
Step-by-step explanation:
The expression 14.97n + 29 represents the amount of money, in dollars, that Gabe spent at a store in the mall, where n denotes the number of items he bought. To find out the total cost of his shopping trip, we have to multiply the number of items Gabe bought by 14.97 and then add 29 to that product. For example, if Gabe bought 5 items, the calculation for the total cost would be 14.97 × 5 + 29 = 74.85 + 29 = $103.85. This expression can be used to quickly calculate Gabe's total spending at that store based on the quantity of items purchased.
