On Monday, the regular price of a widget was discounted by 25 percent. On Tuesday, the reduced price was discounted by 50 percent. If the final price was $60, what was the regular price?
A. $135
B. $150
C. $160
D. $175
E. $180
Almost no calculation
Let original price = x
25% discount on Monday = 75% of x = \(\frac{3}{4}x\)
50% of Monday price = \(\frac{1}{2}\)*\(\frac{3}{4}x\)=\(\frac{3}{8}x\)
