Ashlyn · Answer 1

Percent formula : is/of = %/100

is = 17.4

% = 25

of = x

now we sub

17.4 / x = 25/100

since this is a proportion, we cross multiply

(25) (x) = (17.4) (100)

25x = 1740

x = 1740/25

x = 69.6 < = = = ur answer

Since 17.4 is equivalent to 25% of a number, and if there are four 25%s to equal a 100%, all you would need to do in this problem is multiply 17.4 by 4 in which will give you the number: 69.6. And so the answer is c. 69.6
