Abel, Belle, and Cindy have $408 altogether. belle has $7 more than Cindy and $5 more than Abel. How much does Abel have.

Abel has $135. You can solve this using system of equations.

You know that the money from A (Abel) + B (Belle) + C (Cindy) = $408

You also know that B = C + 7 and B = A + 5, because Belle has $7 more than Cindy and $5 more than Abel. Just switching the numbers around, C = B - 7 and A = B - 5. Now you can plug A and C back into the first equation to solve for B.

(B - 5) + B + (B - 7) = 408

3B - 12 = 408

B = 140

We know that A = B - 5, so Abel has $140 - $5, which is $135.

Abel has 36 dollers because

7+5=12

408-12=36
