Answer
$179$
Work Step by Step
Our sales, growing every 6 months, can be considered as an investment. We know that the future value of it can be calculated as:
$FV=PV\times (1+r)^{t}$
Here, the present value, the number of sold kits in the first month is $100$.
The future value is number of sold kits this month is the question.
The compound rate is $r=6\%$
The number of 6-months periods is $5\times 2$ , therefore $t=10$
Therefore the future value is:
$FV=PV\times (1+r)^{t}=100\times (1.06)^{10}\approx 179$
