Question

Carmela is growing her hair to donate to a charity. The hair must be a minimum length of 10 inches. Her hair is already 4 inches long. If hair grows at the rate of 6 inches a year, write and solve an inequality to find the minimum number of years she must grow her hair to be able to make a donation.

Answer 1

It's kind of important to know how long it's been since her last cut but...
y=years
6y+4=10
I think that would work.
