Question

Barry bought 21.50 meters of light rope at 0.46 per meter and three meters of heavy rope at 1.04 per meter. How much did he get back from three 5 dollar bills

Answer 1

To find out how much Barry spent and how much change he received from his three $5 bills, we can follow these steps:

1. **Calculate the cost of the light rope:**
\[
\text{Cost of light rope} = 21.50 \, \text{meters} \times 0.46 \, \text{per meter} = 9.89
\]

2. **Calculate the cost of the heavy rope:**
\[
\text{Cost of heavy rope} = 3 \, \text{meters} \times 1.04 \, \text{per meter} = 3.12
\]

3. **Calculate the total cost:**
\[
\text{Total cost} = \text{Cost of light rope} + \text{Cost of heavy rope} = 9.89 + 3.12 = 13.01
\]

4. **Calculate the amount Barry paid with three $5 bills:**
\[
\text{Total amount paid} = 3 \times 5 = 15.00
\]

5. **Calculate the change received:**
\[
\text{Change} = \text{Total amount paid} - \text{Total cost} = 15.00 - 13.01 = 1.99
\]

Therefore, Barry got back **$1.99**.
