We can set up a proportion since we know the ratio between the # of purple marbles and the # of green marbles.
A ratio is a way to compare two different values: for every 8 purple marbles there are 5 green marbles
<h2>
</h2><h2 /><h2>when we cross multiply, we get 5p = 240 </h2><h2>we divide both sides by 5 to isolate the variable </h2><h2 /><h3><u>There are 48 purple marbles </u></h3>
Answer:
Percent off is 28%
Step-by-step explanation:
Cost of Television = $1420
Cost of Television after store sale =$1022.40
Drop in price= 1420-1022.40= 397.60.
Price taken off = $ 397.60.
Percentage taken off= \frac{Difference }{original} x 100.
= \frac{397.60}{1420} x 100=28%.
