The new price is \$50. It got reduced by 30% to get to \$50. What is the original price? I just can't get my head around this. Can anyone give me a hand please? Thanks. Last edited by skipjack; May 18th, 2019 at 05:10 PM.

If so, then the new price of 50 dollars is 70% of the original price. Letting x be the original price ... 0.70x = 50 dollars Solve for x. Last edited by skipjack; May 18th, 2019 at 05:11 PM.

30% of a number is 30 ━━ = 0.30 times that number. 100 30% of "X" is 0.30X. Taking 30% off X is X  0.30X = (1  0.30)X = 0.70X. That is equal to \$50, so 0.70X= \$50. To find X, divide by 0.70: X = \$50 / 0.70 Last edited by skipjack; May 18th, 2019 at 05:04 PM.
