Question

Tabitha earned 60$ in February. she earned 90$ in March. what is the percent increase or decrease in tabithas monthly earnings? pls help i havent learned percentages yet

Answer 1

50% increase

Explanation:

Hey there!

I see you haven't learned percentages yet.

Well here is a simple formula for finding percentage increase:

`((final-start))/(|start|) *100`

In this case, the start value is 60 and the end value is 90

If we input these values into the formula we get

`(90-60)/(|60|)*100`

And now we just simplify

`(30)/(60)*100\\ 1/2*100\\50`

And in this case since we are talking about percentages,

The percent increase that Tabitha gets is 50%
