<result>A</result>
the price of a certain product increased by the same percent from 1960 to 1970 as from 1970 to 1980. if its price of $ 1.20 in 1970 was 150 percent of its price in 1960, what was its price in 1980?
multiply(divide(150, const_100), 1.2)
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 = $ 1.2 * 1.5 = $ 1.8 . answer : a .
