Frank worked 8hours on the first four days of the week and 9hours on the fifth day he did this for 4weeks in a row. how many total hours did frank work

Total number of hour worked by Frank is 164 hours .

Step-by-step explanation:

Given as :

The number of hours worked by Frank on the first four days = 8 hours

So, Total number of hour worked by Frank on 4 days = 8 hours × 4 = 32 hours

The number of hours worked by Frank on the fifth day = 9 hours

So, Total number of hour worked by Frank in one week = total 4 day work + 5th day work

I.e  Total number of hour worked by Frank in one week = 32 hours + 9 hours

Or, Total number of hour worked by Frank in one week = 41 hours

Again

Total number of weeks the Frank worked = 4 weeks

So, Total number of hour worked by Frank in all 4 week = 41 hours × 4

i.e  Total number of hour worked by Frank in all 4 week = 164 hours

Hence,Total number of hour worked by Frank is 164 hours . Answer

Frank worked for 68 hours in 4 weeks.

Step-by-step explanation:

Given:-

Working hours of Frank on first 4 working days = 8 hours.

Working hour  of Frank on fifth day = 9 hours.

To find:- Working hours for 4 weeks= ?

Solution:-

Working hours for 1 week = working hour on first 4 days of week + working hours on fifth day of week

Working hours for 1 week = 8+9

Working hours for 1 week = 17 hours per week.   -----------(1)

Now,

Working hours for 4 week = 4 working hours for 1 week

Working hours for 4 week =   ----------(from 1)

Working hours for 4 week = 68 hours.

Therefore Frank worked for 68 hours in 4 weeks.
