Question

Can't anyone here show me how to solve this Please help me solve this
For health insurance under plan B I would pay the first $120, but only 20% of the rest. Assuming I have over $120 in medical bills I would save with plan B if I had more than $______ in medical bills

Answer 1

What is plan A?

Answer 2

ok plan A is I would have to pay the first $90, plus 25% of the rest

Answer 3

Plan A equation: y = 90 + .25x

Can you do plan B equation?

Answer 4

would it be y=120 + .20x

Answer 5

Yes, not set them equal to one another

90 + .25x = 120 + .20x

subtract .20x from both sides

90 + .05x = 120

can you solve for x here?

Answer 6

1x=600

Answer 7

Yes, therefore, plan B is better when your medical bills exceed $600. Excellent!
