The cost of a jacket increased from $90.00 to $103.50. What is the percentage increase of the cost of the jacket?
a_sh-v [17]

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 %
