In order to calculate the amount Gerald will have to pay, we first see the amount that he has to pay for his current plan, the dental plan and the vision premium. He has to pay 35% of the $345 monthly health insurance premium, which is $120.75. Next, he will have to pay 50% of the $38 of his dental plan, which is $19. Finally, he will have to pay 25% of the $23 of the vision plan, which is $5.75. The total that Gerald will pay will be the sum of these amounts, that is: 120.75 + 19 + 5.75 = $145.50
