To find the lowest price of one dish and separately for 10 dishes of Eggs with Bacon during the week, we need to calculate the cost for these quantities each day based on the given prices. Remember, the cost of a dish is derived from the price of 2 eggs and 1 loaf of bacon.
Let's break down the calculations in categories: the cost for one dish each day, and the cost for 10 dishes each day. For 10 dishes, it's worth evaluating if buying stacks of 20 (for both eggs and bacon) and potentially having leftovers is more economical than buying per piece.
The cost of one dish = (2 * Price per egg) + Price per loaf of bacon
Day of the week | Cost per dish (2 eggs + 1 bacon) |
---|---|
Sunday | (2 * 1) + 3 = 5 |
Monday | (2 * 2) + 2 = 6 |
Tuesday | (2 * 3) + 4 = 10 |
Wednesday | (2 * 4) + 3 = 11 |
Thursday | (2 * 3) + 3 = 9 |
Friday | (2 * 2) + 3 = 7 |
Saturday | (2 * 2) + 3 = 7 |
For a single dish, Sunday is the cheapest day at $5.
10 dishes require 20 eggs and 10 loafs of bacon.
Option 1: Buy per piece
- Cost (20 eggs and 10 loafs of bacon) = (20 * Price per egg) + (10 * Price per loaf of bacon)
Option 2: Buy per stack where economical (especially for eggs)
- For eggs, buying a stack of 20 might be cheaper some days.
- For bacon, since we need 10 loaves, we'll check if buying a stack is more economical or buying per piece.
Let's compare these two options:
Day of the week | Cost per 10 dishes (Option 1) | Cost per 10 dishes (Buying Stacks) |
---|---|---|
Sunday | (20 * 1) + (10 * 3) = 50 | 10 + 15 = 25 |
Monday | (20 * 2) + (10 * 2) = 60 | 9 + 15 = 24 |
Tuesday | (20 * 3) + (10 * 4) = 100 | 8 + 15 = 23 |
Wednesday | (20 * 4) + (10 * 3) = 110 | 7 + 13 = 20 |
Thursday | (20 * 3) + (10 * 3) = 90 | 6 + 15 = 21 |
Friday | (20 * 2) + (10 * 3) = 70 | 8 + 15 = 23 |
Saturday | (20 * 2) + (10 * 3) = 70 | 9 + 15 = 24 |
For 10 dishes, Wednesday is the cheapest day at $20, when purchasing stacks.
- The cost for one dish is lowest on Sunday at $5 per dish.
- The cost for 10 dishes is lowest on Wednesday at $20 total when buying in stacks.
