Question

If Sue worked 6 3/4 hours on Monday, 4 hours on Tuesday, 7 3/4 hours on Wednesday, 8 hours on Thursday, and 5 1/2 hours on Friday, calculate her weekly wage at $7.20 per hour.

Answer 1

$230.40 is the answer.

Answer 2

Answer: Total weekly cost was $230.4.

Explanation:

Since we have given that

Number of hours Sue worked on Monday =
`6(3)/(4)=(27)/(8)\ hours`

Number of hours Sue worked on Tuesday = 4 hours

Number of hours Sue worked on Wednesday =
`7(3)/(4)=(31)/(8)\ hours`

Number of hours Sue worked on Thursday = 8 hours

Number of hours Sue worked on Friday =
`5(1)/(2)=(11)/(2)\ hours`

So, Total number of hours in all five days is given by

`(27)/(4)+4+(31)/(4)+8+(11)/(2)\\\\=12+(27+31)/(4)+(11)/(2)\\\\=12+(58)/(4)+(11)/(2)\\\\=12+(58+22)/(4)\\\\=12+(80)/(4)\\\\=12+20\\\\=32`

Cost of her wage per hour = $7.20

Total weekly wage is given by

`32* 7.20\\\\=\$230.4`

Hence, Total weekly cost was $230.4.
