Answer:
$75,000
Explanation:
Given that,
Factory maintenance = $50,000;
Machine setup = $100,000;
Heating and lighting = $25,000
Machine repair = $10,000
Therefore,
Total costs are as follows:
= Factory maintenance + Heating and lighting
= $50,000 + $25,000
= $75,000
Therefore, the total costs in the plant services activity are $75,000.
