To calculate, for example, a new price after a price increase of 65%, multiply the original price by 1.65 (100%+65% = 165% = 1.65).

To calculate, for example, a new price after a price reduction of 32%, multiply the original price by 0.68 (100%-32% = 68% = 0.68).

In this problem....

(1) original cost to the store: 800
(2) original price (70% over cost): multiply (1) by 1.70
(3) price on January 1 (sale 15% off): multiply (2) by 0.85
(4) price on January 10 (increase 10%): multiply (3) by 1.10

You can do the calculations....
