Question

An electronic device that previously sold for $21 has been reduced to $17.43. The price reduction, rounded to the nearest whole percent, is

A. 17%.
B. 20%.

C. 21%.

D. 83%.

Answer 1

A. 17%
because you would do:
(21-17.43)/21 = .17 = 17%

Answer 2

OK, so 75% of 20 is 15; you multiply 20 by 0.75. So to answer this question you first have to solve N*21 = 17.43, or N=17.43/21; this is 0.83. This means that the end price was 83% of the original, which means that the reduction was 100-83 = 17%

Answer 3

Ok. Start by taking your original cost, which in this case is $21.00. Subtract the new price from the original, e.g. 21-17.43. This gives you the difference (3.57), which is also known as the price reduction. Next you have to convert this price reduction into a percent of the original price (also known as the whole percent). To do this, take the price reduction and divide it by the original price, eg. 3.57/21. Then multiply the result (0.17) by 100. This gives you the whole percent (17%)

Answer 4

Price reduction = 21 -17.43
= $3.57

Percentage of price reduction = (3.57/21)*100
= 17%

Option A.

Answer 5

21 - 17.43 = 3.57/ 21 = .17 x 100 = 17%

Letter A is the answer

Answer 6

($21 - 17.43)/$21 * 100%
= ($3.57/$21) * 100%
= 0.17 * 100%
= 17%
price has been reduced by 17%

Answer 7

21 - 17.43 = 3.57

3.57 / 21 = 17%

Answer 8

17.43/21*100%=83%

100%-83%=17%

A

Answer 9

Price reduction is 21-17.43 = 3.57
21 * X= 3.57
X=3.57/21
X=0.17
X= 0.17 *100
X=17%

Answer 10

17.43/21 = 0.83

1 - 0.83 = 17% A
