Answer 1

`Maintenance = 55\%`

Explanation:

Given

`Time = 40\ hours`

`Register = 15\%`

`Greetings = 30\%`

Required

Percentage of time spent in maintenance;

From the given parameters,She spends the rest of her time in maintenance;

This implies that

`Register + Greetings + Maintenance= 100\%`

Substitute 15% for Register and 30% for Greetings

`15\% + 30\% + Maintenance= 100\%`

`45\% + Maintenance= 100\%`

Subtract both sides by 45%

`45\% - 45\% + Maintenance = 100\% - 45%`

`Maintenance = 100\% - 45%`

`Maintenance = 55\%`

Hence, the percentage of time spent in Maintenance is 55%
