Question

The price of an item yesterday was $135 . Today, the price rose to $216 . Find the percentage increase.

Answer 1

Answer:

Percentage Increase = 60%

Step-by-step explanation:

To find the percentage increase, we will use the formula below;

Percentage Increase = $\frac{Increase}{Initial cost}$  ×   100%

From the question given,  the initial cost = $ 135

Now, we need to find the increase;

Increase = $216 - $135 = $81

We can now proceed to insert the values and then simplify;

Percentage Increase = $\frac{Increase}{Initial cost}$  ×   100%

                                    =$\frac{81}{135}$  ×   100%

                                        =$\frac{8100}{135}$ %

                                        =60%

Percentage Increase = 60%
