Marcus' employee benefits include family health care coverage. He contributes 25% of the cost. Marcus gets paid weekly and $102
ArbitrLikvidat [17]

Monthly amount, M = $102×4 = $408.

Also, yearly amount, Y = M×12 = $408×12 = $4896

It is given that 25% of the cost is contributed by Marcus.

Amount Marcus paid

=\dfrac{\$4896 \times 25 }{100}\\\\= \$1224

Therefore, his employer contribution annually for coverage is $( 4896 - 1224)=$3672.

Hence, this is the required solution.

Tell whether the sequence is arithmetic. If it is, what is the common difference?
Ilya [14]
The answer is B. Yes; 4

Arithmetic sequence is the type of sequence of numbers which difference between each number will always remain constant
in the sequence above we could see the difference between one number with another is exactly 4:

15 + 4 = 19

19 + 4 = 23

23 + 4 = 27
