Which is a better buy? 3 apples for 1.24 or 5 apples for 2.53. in unit rates

Well,
     if you do the first option, each of the 3 apples is going to be about 41 cents.
     If you do the second option, each of the 5 apples will cost about 50 cents.
So, the first option would be your best bet.

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
