ou purchase 6 sleeping bags and 4 flashlights for a camping trip. Then you find out that more people are coming on the trip, so you buy 5 more sleeping bags and 3 more flashlights. Define and use variables to represent the total cost.

Final answer:

To calculate the total cost, we need to determine the cost of each sleeping bag and flashlight and then add the costs of the initial purchase and the additional items.

Step-by-step explanation:

To calculate the total cost, we need to first determine the cost of each sleeping bag and flashlight. Let's assume sleeping bags cost $30 each and flashlights cost $10 each. In the initial purchase, you buy 6 sleeping bags and 4 flashlights, so the total cost would be:
6 x $30 (cost per sleeping bag) + 4 x $10 (cost per flashlight) = $180 + $40 = $220.
After finding out that more people are coming, you purchase 5 more sleeping bags and 3 more flashlights. The cost of these additional items would be:
5 x $30 (cost per sleeping bag) + 3 x $10 (cost per flashlight) = $150 + $30 = $180.
To calculate the total cost, we add the cost of the initial purchase and the cost of the additional items:
$220 (initial purchase) + $180 (additional items) = $400.

Final answer:

The total cost of purchasing sleeping bags and flashlights can be calculated using variables representing the costs of each item. Variables 's' and 'f' are used for the cost of a single sleeping bag and flashlight, respectively, and by buying certain quantities initially and then additional quantities later, the total cost can be figured out.

Step-by-step explanation:

To calculate the total cost of purchasing sleeping bags and flashlights, we can define variables to represent the cost of a single sleeping bag and a single flashlight. Let s be the cost of one sleeping bag and f be the cost of one flashlight. Initially, 6 sleeping bags and 4 flashlights are purchased, so the initial cost (Time 1 Total Cost) is 6s + 4f. Afterward, 5 more sleeping bags and 3 more flashlights are purchased, so the additional cost (Time 2 Total Cost) is 5s + 3f. To find the total cost for all items, we add the initial and additional costs together, which gives us (6s + 4f) + (5s + 3f) = 11s + 7f.

By substituting realistic prices for s and f, the total expenditure can be calculated. If the list of products were longer and included more realistic prices, the total quantity spent could be a precise number, reflecting the actual expense incurred from the purchases made for the camping trip.
