The price of a certain product increased by the same percent from 1960 to 1970 as from 1970 to 1980. If its price of $1.30 in 1970 was 150 percent of its price in 1960, what was its price in 1980?
Choose the correct choice from the following options
A) a) $ 1.80 B) b) $ 1.95 C) c) $ 2.40 D) d) $ 2.70 E) e) $ 3.00
The price in 1970 was 150 percent of its price in 1960, means that the percent increase was 50% from 1960 to 1970 (and from 1970 to 1980).   Therefore the price in 1980 = $1.3*1.5 = $1.95.   Answer: b) $ 1.95.
