Answer:

So the Percentage Increase = 15 %

Step-by-step explanation:

Given:

Original price = $ 90.00

New Price = $103.50

To Find:

Percentage Increase = ?

Solution:

Percentage Increase $=\frac{Difference in Value* 100}{Original value}$ %

Now In our Given Data

Difference in Value = New Value - Original Price

Putting in the values

Difference in Value = 103.50 - 90.00

= $13.50

Now we Know all the value and the formula is

Percentage Increase $=\frac{Difference in Value* 100}{Original value}$ %

Putting in the values

Percentage Increase $=\frac{13.50* 100}{90.00}$ %

$=\frac{1350}{90.00}$ %

= 15%

which tells us that

Percentage Increase = 15 %
