Answer

Shelby and Tyler could receive change in various combinations of bills and coins, such as: - $5: 1 five-dollar bill, 2 one-dollar bills, or 1 one-dollar bill and 4 quarters. - $2: 1 two-dollar bill or 2 one-dollar bills. - $1: 1 one-dollar bill, 4 quarters, 10 dimes, 20 nickels, or 100 pennies. The exact change depends on the total cost of their purchases.

Solution

To determine what bills and coins Shelby and Tyler could receive in change after spending $20, we first need to establish the total cost of their purchases. However, since the problem does not provide the individual prices of the items, we will assume that the total cost is less than $20, allowing us to calculate the change they would receive. Let's denote the total cost of their purchases as \( C \). The change they would receive can be calculated as: \[ \text{Change} = 20 - C \] ### Step 1: Identify Possible Total Costs Since we don't have specific prices, let's consider a few hypothetical total costs for \( C \): 1. If \( C = 15 \): \[ \text{Change} = 20 - 15 = 5 \] 2. If \( C = 18 \): \[ \text{Change} = 20 - 18 = 2 \] 3. If \( C = 19 \): \[ \text{Change} = 20 - 19 = 1 \] ### Step 2: Determine Possible Change Combinations Now, let's explore the possible combinations of bills and coins for each change amount. 1. **For $5 Change:** - 1 five-dollar bill - 5 one-dollar bills - 1 one-dollar bill and 4 one-dollar coins - 2 two-dollar bills and 1 one-dollar bill 2. **For $2 Change:** - 1 two-dollar bill - 2 one-dollar bills - 1 one-dollar bill and 1 one-dollar coin 3. **For $1 Change:** - 1 one-dollar bill - 4 quarters - 10 dimes - 20 nickels - 100 pennies ### Conclusion Without specific prices for the items, we can conclude that Shelby and Tyler could receive various combinations of bills and coins as change depending on the total cost of their purchases. The examples above illustrate how they could receive change for different total costs. If you have specific prices for the items, please provide them, and I can calculate the exact change they would receive.

Beyond the Answer

First, let's break down their total spending! Assuming each cup of soup is $3, the salad costs $4, each piece of fruit is $1, each sandwich is $5, and each drink is $2. Their total would be: \( 2(3) + 4 + 2(1) + 2(5) + 2(2) = 6 + 4 + 2 + 10 + 4 = 26 \). Since they gave $20, they actually still owe $6, so no change would be given. Now, let's consider what mistakes they might have made. They could have miscalculated the prices or chosen too many items without realizing they didn’t have enough money. It’s important to double-check your items against your budget before reaching the cashier!
