If Marty earns 24 per hour. Marissa earns a base weekly salary of 100 plus 8 per hour. How long will Marty and Marissa have to work to earn the same amount of money?

Let ( h ) be the number of hours worked. Marty's earnings are ( 24h ), while Marissa's earnings are ( 100 + 8h ). To find when they earn the same amount, set the equations equal:

[ 24h = 100 + 8h ]

Solving this gives:

[ 16h = 100 ] [ h = 6.25 ]

Marty and Marissa will have to work 6.25 hours to earn the same amount of money.
