Q:

he value of an autographed baseball from 2017 is $300. The value of the baseball exponentially increases by 5% each year after 2017. Write a one-variable inequality that could be used to solve for the number of years, x, it would take for the baseball to be worth at least $650. Do not use any dollar signs in the inequality. Write the inequality in standard form.

Accepted Solution

A:
If the ball increases by 5% each year, then it's value over t years would be:
fv=300*(1+.05)^t, where fv  is future value. So:
300*(1.05)^t=650
1.05^t=2.166667
t=15.85 years
