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.
