Answer:

13

Step-by-step explanation:

If E is the midpoint, Then DE = FE

=> x+5 = 3x+2

=> 3x-x = 5-2

=> 2x = 3

=> x = 3/2

<u><em>Now DF:</em></u>

=> 3/2 + 5 + 3(3/2)+2

=> (3+10)/2 + (9+4)/2

=>  (13+13)/2

=> 26/2

=> 13

Shashi Rimoko earns $620 per week as a chef. He has group
finlep [7]

Out of the weekly amount that Shashi Rimoko makes, a deduction of $37.93 is made for insurance.

The total Medical cost is $9,560 and out of this, the amount paid by Shashi per year is:

<em>= Amount x (1 - percentage paid by restaurant)</em>

= 9,560 x ( 1 - 80%)

= $1,912

The amount he pays for Dental coverage is:

<em>= Amount x (1 - percentage paid by restaurant)</em>

= 172 x (1 - 65%)

= $60.20

The total amount he pays for insurance per year is:

<em>= Medical + Dental </em>

= 1,912 + 60.20

= $1,972.20

The weekly deduction is:

<em>= Year amount / No. of weeks in year </em>

= 1,972.20 / 52

= $37.93

In conclusion, $37.93 is deducted from his paycheck every week.
