: Alice went shopping on Saturday for a dress at a store where everything was on sale for 30% off the regular price. If the dress she bought had a regular price of $37.50 and the sales tax is 8%, how much did Alice pay for the dress on Saturday?
Amount she saved from the 30% off sale.
$37.50 × 0.30 = $11.25
Then the sale price will be $37.50 - $11.25 = $26.25
Now, find 8% tax on $26.25
$26.25 × 0.08 = $2.10
Add the tax.
$26.25 + $2.10 = $28.35
Alice paid $28.35
for the dress she bought Saturday.
Nancy is taking an online survey with 300 questions. She is able to respond to 15 questions per minute. How long will it take Nancy to complete the entire survey?
Let x = the amount of time
15 questions: 1 minute = 300 question: x
Cross multiply and solve for x
15 * x = 300 *1
So x = 20
Nancy will take 20 minutes
