Sale prices: find the original price<\/strong><\/h2>\n\n\n\n

Key notes:<\/p>\n\n\n\n

\n

The sale price is equal to the percent paid times the original price.<\/p>\n\n\n\n

sale price = percent paid original price<\/p>\n\n\n\n

Find the percent paid:<\/p>\n\n\n\n

To find the percent paid, subtract the percent off from 100%.<\/p>\n\n\n\n

percent paid = 100% \u2013 percent off<\/p>\n\n\n\n

= 100% \u2013 90%<\/p>\n\n\n\n

= 10%<\/p>\n\n\n\n

With 90% off, the percent paid is 10%.<\/p>\n\n\n\n

Write an equation to solve for the original price:<\/p>\n\n\n\n

Since 10% of the original price is equal to the sale price of \u20b988, you can set up and solve an equation. Let p represent the original price.<\/p>\n\n\n\n

10% . p = 88<\/p>\n\n\n\n

10 \/ 100 . p = 88 Write the percent as a fraction<\/p>\n\n\n\n

0.1 . p = 88 Write the fraction as a decimal<\/p>\n\n\n\n

0.1p \/ 0.1 = 88 \/ 0.1 Divide both sides by 0.1<\/p>\n\n\n\n

p = 880 Simplify<\/p>\n\n\n\n

The original price was \u20b9880.<\/p>\n<\/div><\/div>\n\n\n\n

\u20b9______<\/p>\n<\/div><\/div>\n\n\n\n

Find the percent paid:<\/p>\n\n\n\n

To find the percent paid, subtract the percent off from 100%.<\/p>\n\n\n\n

percent paid = 100%\u2013percent off<\/p>\n\n\n\n

= 100% \u2013 25%<\/p>\n\n\n\n

= 75%<\/p>\n\n\n\n

With 25% off, the percent paid is 75%.<\/p>\n\n\n\n

Write an equation to solve for the original price:<\/p>\n\n\n\n

Since 75% of the original price is equal to the sale price of \u20b9495, you can set up and solve an equation. Let p represent the original price.<\/p>\n\n\n\n

75% . p = 495<\/p>\n\n\n\n

75 \/ 100 . p = 495 Write the percent as a fraction<\/p>\n\n\n\n

0.75 . p= 495 Write the fraction as a decimal<\/p>\n\n\n\n

0.75p \/ 0.75 = 495 \/ 0.75 Divide both sides by 0.75<\/p>\n\n\n\n

p = 660 Simplify<\/p>\n\n\n\n

Find the percent paid:<\/p>\n\n\n\n

To find the percent paid, subtract the percent off from 100%.<\/p>\n\n\n\n

percent paid = 100% \u2013 percent off<\/p>\n\n\n\n

= 100% \u2013 50%<\/p>\n\n\n\n

= 50%<\/p>\n\n\n\n

With 50% off, the percent paid is 50%.<\/p>\n\n\n\n

Write an equation to solve for the original price:<\/p>\n\n\n\n

Since 50% of the original price is equal to the sale price of \u20b930, you can set up and solve an equation. Let p represent the original price.<\/p>\n\n\n\n

50% . p = 30<\/p>\n\n\n\n

50 \/ 100 . p = 30 Write the percent as a fraction<\/p>\n\n\n\n

0.5 . p = 30 Write the fraction as a decimal<\/p>\n\n\n\n

0.5p \/ 0.5 = 30 \/ 0.5 Divide both sides by 0.5<\/p>\n\n\n\n

p = 60 Simplify<\/p>\n\n\n\n
