Practice 8Quick check
What is \(1\%\) of \(350\)?
One percent is one hundredth: \(350 \div 100 = 3.5\).
Practice 9Quick check
A store takes \(50\%\) off, then another \(50\%\) off the sale price. What is the total discount?
You pay half of half, \(0.5 \cdot 0.5 = 0.25\), so \(25\%\) of the price: a \(75\%\) discount.
All done?
