Final answer:
To calculate each person's share of the $75000 lottery prize, distribute the winnings based on their contributions. Mark and Martha each get $22500, and Mario gets $30000.
Step-by-step explanation:
Mark, Martha, and Mario chipped in to buy lottery tickets with Mark contributing $3 per week, Martha contributing $3 per week, and Mario contributing $4 per week. They won $75000 in one week. The total weekly contribution is $3 (Mark) + $3 (Martha) + $4 (Mario) = $10. To determine the share each person should receive from the $75000 prize, we distribute the winnings based on their weekly contributions.
Mark's share: (3/10) * $75000 = $22500
Martha's share: (3/10) * $75000 = $22500
Mario's share: (4/10) * $75000 = $30000
Mark and Martha will each receive $22500, and Mario will receive $30000.
