Answer:

Expressions greater than 1 are:

5 \div  \frac{9}{10}

2 \frac{3}{2}  \div  1\frac{3}{5}

Step-by-step explanation:

5 \div  \frac{9}{10}

= 5 \times  \frac{10}{9}

=  \frac{50}{9}

= 5.55

___________________________________________

=  \frac{3}{5}  \times  \frac{1}{6}

=  \frac{1}{5}  \times  \frac{1}{2}

=  \frac{1}{10}

= 0.1

________________________________________

\frac{4}{5}  \div  \frac{3}{7}

=  \frac{4}{5}  \times  \frac{3}{7}

=  \frac{12}{35}

________________________________________

2 \frac{3}{5} \div 1 \frac{3}{5}

=  \frac{13}{5}  \div  \frac{8}{5}

=  \frac{13}{5}  \times  \frac{5}{8}

=  \frac{13}{8}

= 1 \frac{5}{8}

________________________________________

\frac{12}{5}  \div  \frac{13}{5}

=  \frac{12}{5}  \times  \frac{5}{13}

=  \frac{12}{13}

Jim and Stephanie just got married and are thinking about changing their health care insurance plans to be more affordable. Curr
insens350 [35]

Answer:

Option B is correct.

Stephanie should add Jim to her health care plan.

Step-by-step explanation:

Let's take the options one by one.

Option 1

If Jim's employers insure him and his wife.

Jim’s employer pays 42% of his $378 monthly premium. His insurance plan will also pay for 23% of the $345 premium for additional beneficiaries.

It means Jim will pay (0.58 of $378) for himself plus (0.73 of $345) for his wife.

Amount Jim pays = (0.58 × 378) + (0.73 × 345) = $471.09

Option 2

If Stephanie's employers insure both of them.

Stephanie’s employer pays 35% of her $298 monthly premium but offers to pay an extra 10% of her premium for each beneficiary Stephanie adds to her plan. Her employer would then pay 30% of the $349 premium for each additional beneficiary.

It means Stephanie would pay (0.65 of $298) she'll pay for herself plus (0.70 of $349) she'll pay for her husband minus (10% of $298) that her company wants to pay out of the insurance fee of any of her additional beneficiary.

Amount Stephanie will pay = (0.65 × 298) + (0.70 × 349) - (0.10 × 298) = $408.2

Option 3

If each of them does an insurance plan with their respective employers

Jim’s employer pays 42% of his $378 monthly premium.

Stephanie’s employer pays 35% of her $298 monthly premium

Jim would pay (0.58 × $378) for himself = $219.24

Stephanie would pay (0.65 × $298) for herself = $193.7

Total they would pay in this option = $219.24 + $193.7 = $412.94

Of all the three options, the option that minimizes their expenses is when Stephanie insures herself and Jim with her employers for a total cost of $408.2 compared to a total cost of $471.09 if Jim insures the two of them with his employers or $412.94 if they respectively insure each other with their respective employers.

Hope this Helps!!!
