If paper was £1.99 a pack and is now £3.98 a pack, what is the percentage increase in the price of the product?

spayn [35]

Answer:

100%

Step-by-step explanation:

The initial price of the paper = 1.99

The final price of the pack of paper = 3.98

We need to find the percentage increase in the price of the product. It can be solved as follows :

$\%=\dfrac{3.98-1.99}{1.99}\times 100\\\\=100\%$

So, the percentage increase in the price of the product is 100%.
