Answer 1

To find the total cost of 10 bottles of juice, each costing a dollar and 15 cents, Justin can use the following method:

1. **Convert the price into cents:**
A dollar is 100 cents, so a dollar and 15 cents is:
\[
100 \text{ cents} + 15 \text{ cents} = 115 \text{ cents}
\]

2. **Multiply by the number of bottles:**
Now multiply the price in cents by the number of bottles (10):
\[
115 \text{ cents} \times 10 = 1150 \text{ cents}
\]

3. **Convert back to dollars:**
Finally, convert the total cost back to dollars:
\[
1150 \text{ cents} = 11.50 \text{ dollars}
\]

So, Justin can conclude that the total cost of the 10 bottles of juice is $11.50 using this method.
