A retired math teacher takes her nephew shopping. She tells her nephew that they can spend x dollars and x-67.6% = 13. What operation does the nephew need to use to find how much money they can spend?

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

45 this is because of the agarose

58 i think in 5 hours he makes $58
