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.
