Question

There is a hot market at school for used graduation gowns, in fact the price is growing exponentially! Last week I could have gotten one for $25, but today, one week later, the price is $37.50. What would the price be if I decide to wait to buy my graduation gown at graduation, six weeks from now?

Answer 1

$100

Explanation:

the equation to solve this is:

`y=12.5x+25`

`y=12.5x+25\\ =(12.5*6)+25\\ =75+25\\ =100`

(Assuming, of course, that this is a homework assignment and not you actually buying it cuz' in real life the numbers would be different from month to month)
