1. To find the percent decrease, you would first subtract the new value from the original value, and then divide that result by the original value. Finally, you multiply the quotient by 100 to get the percentage.

In this case, the original value is 75 and the new value is 60.
(75 - 60) / 75 = 15 / 75 = 0.2
0.2 x 100 = 20%

So, the percent of decrease is 20%. Therefore, the correct option is A.

2. To find the percent markup, you would first subtract the cost from the selling price, then divide that result by the cost. Finally, you multiply the quotient by 100 to get the percentage.

In this case, the cost is $100.00 and the selling price is $160.00.
(160 - 100) / 100 = 60 / 100 = 0.6
0.6 x 100 = 60%

So, the percent markup is 60%. Therefore, the correct option is B.

3. To find the sale price, you would first calculate the discount amount by multiplying the regular price by the percent of discount. Then, you subtract the discount amount from the regular price to get the sale price.

In this case, the regular price is $57.63 and the percent of discount is 10%.
Discount amount = $57.63 x 0.10 = $5.763

Sale price = $57.63 - $5.763 = $51.867
Rounding to the nearest cent, the sale price is $51.87. Therefore, the correct option is C.

4. To find the sale price, you would first calculate the discount amount by multiplying the regular price by the percent discount. Then, you subtract the discount amount from the regular price to get the sale price.

In this case, the regular price is $56.00 and the percent discount is 40%.
Discount amount = $56.00 x 0.40 = $22.40

Sale price = $56.00 - $22.40 = $33.60
Rounding to the nearest cent, the sale price is $33.60. Therefore, the correct option is D.

1. (60/75)*100% = 80 %.

80% - 100% = -20% = 20% Decrease.

2. (160/100)*100% = 160%
160% - 100% = 60% Increase.

3. %Cost = 100% - 10% = 90%
Cost = 0.90 * 57.63 = $51.87

4. Same procedure as #3.
