Jewel · Answer 1

The sales revenue will increase by 60%

Explanation:

Let's work this as the amount of sales were 1 units:

Price when to 3.10 dollars from 1.55

And quantity from 1 untis to "0.8 unit"

So revenue before price changes: 1.55 x 1 = 1.55

Revenue after price changes: 3.10 x 0.8 = 2.48

The percentaje in sales revenue will be.

new price sales / old price sales - 1 = 2.48 / 1.55 - 1 = 0.6

We can conclude the sales revenue will increase by 60%
