Question

Lisa spent $67 for a skateboard and $25 for a protective helmet.

What percent of the total amount that Lisa spent was the price of the skateboard? Round to the nearest tenth of a percent, if necessary

Answer 1

First we need to find the total amount then we can find what % of that the skateboard is.

To find the total we do: \[Total = Skateboard + Helmet\]\[T=S+H\]

Then you can find the percentage by dividing the host of the skateboard into the total cost:
\[P_{skateboard} = \frac{skateboard}{total} \times 100\]

Answer 2

73%
