Two problems

James -Parent of homeschooled student, level 10-12.

Casey is a finanical consultant for ABC finance. She earns $456.21 weekly. Her annual group medical coverage costs $1942, of which ABC pays 65%. How much is deducted weekly for medical coverage?

and:

Eleanor demonstrates microwaves at the national home show. She is paid $7 for each of the first 7 demonstrations and $11 for each demonstration after 7. What is her commission for a day if she makes 12 demonstrations?

Thank you

Hi James,

In the first problem ABC pays 65% of her group medical premiums so she pays 100% - 65% = 35%. The cost is $1942 and 35% of $1942 is

³⁵/₁₀₀ x $1942 = $679.70 Since there are 52 weeks in a year her weekly deduction for medical coverage will be ^$679.70/₅₂ = $13.07 (Notice that $13.07 x 52 = $679.64 so the employer will probably take 6 cents extra in either the first or last month of the year.)

For the second problem Eleanor makes $7 for each of the first 7 demonstrations she performs for a payment of 7 x $7 = $49. Since 12 - 7 = 5, she performs 5 more demonstrations at $11 each and hence receives 5 x $11 = $55 for these 5 demonstrations. Thus her total commission for the day is $49 + $55 = $104.
