A gallon of gasoline cost 30 cents in 1960 an

$1.30 in 1980

percent increase in the price = ?

first we have to convert cents into dollars so that both amounts have to be in same unit

30 cents = $0.3

increase in gasoline cost = $1.30 - 0.3 = $1

now for calculating percent increase divide this with the new amount and than multiply with 100

percent increase = ($1 / $1.30) x 100 = 76.92% = 77% approx.

so, there is 77% increase in the price of gasoline
