The new price for the jelly cake is $75 as the store increases its purchase price.
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Initial price of jelly cake is = $25.
Increase in price of jelly cake is = 200%.
Hence, increase in price of jelly cake is = $25 × 20%
= $25 × (200/100)
= $25 × 2
= $50.
Hence, the new price for the jelly cake is = initial price + increase in price
= $25 + $50
= $75.
Therefore, the new price for the jelly cake is $75.
