Answer 1

To find the product of $1.39 and 100, Justin can use the property of multiplying by powers of ten. Since 100 is \(10^2\), he can move the decimal point in 1.39 two places to the right.

Therefore, the correct response is:

"He knows that 100 is 10 to the power of 2, so he needs to move the decimal point in 1.39 two places to the right."

This will give him the total cost of the juice bottles.
