Expensive item = $100; Cheap item =$70;

We must increase $70 to$100, so by $30, which is approximately 40% increase: (100-70)/70 = 3/7 = ~0.42. Answer: C. P.S.

A. 22 % B. 30% C. 42 6/7% D. 70% E. 130% You can also use the inverse proportion method outlined by Chris L at Magoosh, https://magoosh.com/gre/2012/inverse-proportions-on-the-gre-the-flip-it-method Assume both items were priced at 100. One is now at 70. If an item has decreased 30%, it is at 70%, or 70/100, or 7/10 of original value. Flip 7/10 to 10/7 in order to figure out by what percent the now-discounted item must increase to return to original value. 10/7 = 1.428571… Ignore the 1 (it's already the value of the item after it has decreased by 30%). .428571.. ≈ 42%.

A. 22 % B. 30% C. 42 6/7% D. 70% E. 130% Let the price of one item be =$100
Price of second item = 30% less than first item = 70% of 100 = $$\frac{70}{100}$$ x 100 = $70 Price to be increased of cheaper item to be equally priced =$ 30
Percent to be increased for less expensive item = 30 = $$\frac{x}{100}$$ x 70
x = $$\frac{30* 100}{70}$$ = 42$$\frac{6}{7}$$%
