N, S , and A have a total of $98 in their wallets. S has $10 less than N. A 4 times what Nicole has. How much does each have?

Question

ending amount of each

Answer 1

N+S+A=98

S=N-10

A=4N

 

Substitute the last two equations into the first to get:

N+(N-10)+4N=98

 

Solve for N, then plug back in to solve for S and A.
