1 answer:
The following questions are related to problems on simple fraction and arithmetic. Hence, the solutions to the questions are as follows :
1.)
Time on mathematics =<em> 1 hour</em>
Time on science homework = <em>7/8</em><em> hours</em>
Total time spent = (1 + 7/8) =
2.)
Total number of students = <em>60</em>
Fraction of girls = <em>3/4</em>
Fraction of boys = 1 - 3/4 = 1/4
Number of boys = 1/4 × 60 = 15 boys
3.)
Initial temperature = <em>- 2°C</em>
Final temperature = <em>8°C</em>
Change in temperature = Final temperature - Initial temperature
Change in temperature = (8 - (-2)) = 8 + 2 = 10°C
4.)
Elevation of everest = <em>20028 feets </em>
Elevation of dead sea =<em> - 485 feets</em>
Difference in elevation = (20028 - (-485)) = 20513 feets
5.)

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
Therefore, his employer contribution annually for coverage is $( 4896 - 1224)=$3672.
Hence, this is the required solution.
