<human>:  Ali, Nada, and John have a total of $67 in their wallets. Ali has $5 less than Nada and John has 4 times more than Nada. How much money does John have?
<bot>: How much money does John have? ** Let's say that N is what Nada has, J is what John has, and A is what Ali has. We know that A = N - 5 and J = 4N.
Write an equation ** We also know that: N + A + J = $67
Write an equation ** We can substitute the equations from step 1 into the equations from step 2 to get: N + 4N + (N-5) = $67
Combine like terms ** Combining like terms gets us 6N - 5 = $67
How much money does Nada have? ** So, N=($67+5)/6 = $12
How much money does John have? ** Substituting $12 back into the equation J = 4 N, we find John has 4 x 12 = $<<4*12=48>>48
