Question

Somebody please help me

Answer 1

80% increase

Explanation:

First, divide $0.25/$0.45, you get 0.8, turn it into a percent. 0.8=80%

There is an 80% increase.

Check work:

0.25x1.8=0.45

We multiply by 1.8 because 80% increase means 100% (itself) multiplied by 80% of itself, which gives us 180% or 1.8.

0.25x1.8=0.45 ✔️

Hope this helps!
