Question

Santa's favorite snack used to cost $1.45 a box. If the cost has gone up 15%, what's the price now?

Answer 1

We know that Santa's favorite snack used to cost $1.45 a box and the cost has gone up 15%. We must calculate the new price.

To calculate the new price we must calculate the 15% of the old price and then add up the old price and its 15%.

1. We must calculate the 15% of the old price

`\text{ \$}1.45\cdot0.15=\text{ \$}0.2175`

2. we must add up the old price and its 15%

`\text{ \$}1.45+\text{ \$}0.2175=\text{ \$}1.6675`

Finally, the price now is $1.6675
