Answer:
The annual maintenance collected in 2008 is $201,000
Explanation:
The computation of the annual maintenance collection is shown below:
For the year 2007
= Annual maintenance × renew percentage
= $2,000,000 × 90%
= $180,000
For the year 2018
= Product sales × paying percentage × purchase percentage
= $2,000,000 × 70% × 15%
= $21,000
So, the annual maintenance collected equals to
= 2017 annual maintenance + 2018 annual maintenance
= $180,000 + $21,000
= $201,000
