Vesnalui [34]

Answer:

14\frac{17}{30}hrs

Step-by-step explanation:

Given parameters:

Time worked on Saturday = 7\frac{11}{12}

Unknown:

Total hours he worked last weekend  = ?

Solution:

Since Brendan worked 84% of the time he worked on Saturday on Sunday;

 Time worked on Sunday  = \frac{84}{100}  x \frac{95}{12}   = \frac{133}{20}  

Total time worked last weekend  = Time worked on Saturday + Time worked on Sunday;

Total time worked  =  \frac{95}{12}  +  \frac{133}{20}  

Total time worked = \frac{475 + 399}{60}

Total time worked  = \frac{874}{60}  

Total time worked = \frac{437}{30}   = 14\frac{17}{30}hrs
