Jamarcus's employer pays 80 percent of his medical insurance. if the insurance costs jamarcus $20 a week, how much is his employer pay­ing?

$80

Step-by-step explanation:

The total amount of his medical insurance is 100%. As such if Jamarcus's employer pays 80 percent , then the amount he pays would be equivalent to 20%.

As such, if the insurance costs Jamarcus $20 a week and the total amount is Y

then,

20% of Y = $20

0.2Y = $20

Y = $100

His employer will be pay­ing

= 80% of $100

= $80

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
