Answer:
The price of an item has risen to $216 today. Yesterday it was $160. The percentage increase is 35%
Solution:
Yesterday, the price of the above mentioned item was $160
Today, the price of the same item has risen to become $216
Thus, percentage increase is price is given as
![P \%=\frac{\text { Difference in price }}{\text { Old price }} * 100](https://img.qammunity.org/2020/formulas/mathematics/college/1mynqxl6t9j6stljet4qs9rmlrtzja0xks.png)
Thus, percentage increase in this case is
![P \%=(\$ 216-\$ 160)/(\$ 160) * 100](https://img.qammunity.org/2020/formulas/mathematics/college/t3zd0al946t2g2y19egjdxe01q6ut0i8uq.png)
![=\left((56)/(160)\right) * 100](https://img.qammunity.org/2020/formulas/mathematics/college/l0p5w2tlqk2oauv8urgd2og92eta6k075e.png)
![0.35 * 100 = 35](https://img.qammunity.org/2020/formulas/mathematics/college/hrboqqigbpik4yr4p8pcnp867726jx2u34.png)
So, the percentage increase in the item of the price from what it was yesterday to what it had risen today is equal to 35%
The percentage increase is 35%.
