Question

The price of a television decreased from $275 to $190 during a clearance sale. Solve for the percent of decrease in the price. Round to the nearest percent, if necessary. A. 29% B. 31% C. 45% D. 69%

Answer 1

Since we know 100% = 100
Take $275 - $190 = $85 , and then use $85 x 100 divided by the amount of $
85 x 100 / 275 = 30.9 Round to the nearest tenths which will equal to 31%. So the answer is B.
