Question

A product costs $60 today. How much will the product cost in t days if the price is reduced by $4 a day

Answer 1

`C=60-4t`

Explanation:

A product costs $60 today.

The price is reduced by $4 a day, so

• a product will cost $60 - $4 = $56 tomorrow;
• a product will cost $56 - $4 = $52 after 2 days;
• a product will cost $52 - $4 = $48 after 3 days;
• and so on

The genaral formula for the price of the product after t days will be

`C=60-4t`
