The formula 1 = prt where i = interest, p = principal, r=rate and t = time is used to calculate the amount of simple interest eamed

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the answer will be

where r the answers
