Your cost c to buy w pounds of walnuts at $6/Ib represented by c = 6w
A truck originally held 24 chairs. You remove 2 chairs at a time. The number of chairs n remaining after you make t trips is represented by n= 24-2t.
The volume V remaining in a 243-ft^3 pile of gravel decreases by 0.2 ft^3 with each shovelful s of gravel spread in a walkway.

The volume V remaining in a 243-ft^3 pile of gravel after spreading s shovelfuls is represented by V = 243 - 0.2s.
To find the total cost c to buy w pounds of walnuts at $6 per pound, you can use the formula c = 6w. This formula represents the cost as a function of the weight of the walnuts. Simply multiply the weight in pounds (w) by the cost per pound ($6) to get the total cost (c).
Now, let's move on to the second problem. The number of chairs remaining, n, after you make t trips can be represented by the formula n = 24 - 2t. In this case, 24 represents the initial number of chairs, and 2t represents the number of chairs removed in each trip (since 2 chairs are removed at a time). Subsequently, the formula subtracts this value from the initial number of chairs to find the remaining number of chairs (n).
Lastly, let's tackle the volume V remaining in a 243-ft^3 pile of gravel with each shovelful, s, of gravel spread in a walkway. The volume decreases by 0.2 ft^3 with each shovelful of gravel. To calculate the remaining volume (V), you can subtract the volume of gravel spread (0.2s) from the initial volume (243-ft^3). This can be represented by the formula V = 243 - 0.2s.
