Answer 1

• Sloan: $40.8

Step-by-step explanation

From the given hours, we have to homogenize the data, for example, all in decimals. Thus:

• Sam:

`7\cdot(1)/(2)=(7\cdot2+1)/(2)=(14+1)/(2)=(15)/(2)=7.50`

• Janet: 6.75

,

• Sloan:

`4\cdot(1)/(4)=(16+1)/(4)=(17)/(4)=4.25`

• Harper

`6\cdot(1)/(2)=(12+1)/(2)=(13)/(2)=6.50`

Then, they earned $300 tips and they spent 20%. Therefore, we have to calculate the 80% that is left after the 20% spent:

`300\cdot0.80=240`

Finally, we have to calculate the proportion of each hour. The total hours are:

`7.50+6.75+4.25+6.50=25`

Then, we have to multiply this quantity times the proportion of Sloan:

`(4.25)/(25)=0.17\cdot240=40.8`
