To find the cost of the flour for each cake, we can follow these steps:
1. Calculate the cost per quarter cup of flour:
 Cost per quarter cup = Cost of the 10-pound bag / Number of quarter cup servings
 Cost per quarter cup = $8.79 / 152
 Cost per quarter cup ≈ $0.0579
2. Convert the amount of flour used for one cake to quarter cups:
 3 3/4 cups = 15 quarter cups
3. Find the total cost of the flour for 10 cakes:
 Total cost = Cost per quarter cup * Quarter cups per cake * Number of cakes
 Total cost ≈ $0.0579 * 15 * 10
 Total cost ≈ $8.685
4. Round the total cost to the nearest cent:
 Total cost ≈ $8.69
Therefore, the cost of the flour for each cake, rounded to the nearest cent, is approximately $8.69. Â
