Answer 1

The price of calculator before 30 years = $30+$122.36 = $145.36

It is given that current price of calculator is after decrease of 532 %

We have to find the price of calculator before 30 years

The price of calculator will be more than 532 % from the current price

So 532% of 23
`=(23* 532)/(100)=$122.36`

So the price of calculator before 30 years = $30+$122.36 = $145.36
