Question

Jack has $6.00 less than twice the amount of money David has. Together they have $45.00. How much money does Jack have

Answer 1

Jack - $28

David - $17

Explanation:

Jack has 2d-6 where d is David's money. David has d money. Together they have 45 and we add the two together.

2d-6+d=45

3d-6=45

3d=51

d=$17

We can then substitute back and find 2(17)-6=34-6=$28.
