To increase an amount by 85%, what single multiplier would you use

the answer to your question is 1.85 Hope this helps! Can I get branliest?

Step-by-step explanation:

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:

if x = 1, then the answer is 3.5
