Question

A diamond ring was reduced from $999.99 to $299.99. Find the percent decrease in the price. Round the answer to the nearest tenth of a percent.

Answer 1

Explanation:

999.99 × x% = 299.99

999.99÷100 × x = 299.99

9.9999 × x = 299.99

9.9999x = 299.99

D.B.S by 9.9999 to make x the subject

9.9999x÷9.9999 = 299.99÷9.9999

x=29.999299993

To the nearest tenth of a percent, x=30

Therefore, x = 30%
