Lester rents his vacation home for 6 months and lives in the home during the other 6 months of 2018. The gross rental income fro
zepelin [54]

Answer:

$ 500

Step-by-step explanation:

Data provided:

Gross rental income from the home = $ 4,500

Real estate taxes for the year = $ 800

Interest per year = $ 3,000

Utilities and maintenance expenses = $ 2,200

Depreciation expense = $ 4,000

Now, for 6 months

Real estate taxes for the year = $ 800 × 0.5 = $ 400  (0.5 as the for half a year i.e 6 months)

Interest per year = $ 3,000 × 0.5 = $ 1500

Utilities and maintenance expenses = $ 2,200 × 0.5 = $ 1,100

Depreciation expense = $ 4,000 × 0.5 = $ 2,000

Thus,

Total expenses for 6 months = $ 400 + $ 1500 + $ 1,100 + $ 2,000 = $ 5000

Therefore,

Net loss from renting his vacation home = Total expenses - Gross income

or

Net loss from renting his vacation home = $ 5000 - $ 4500 = $ 500

Natasha2012 [34]

Answer:

Robin= 750

Sharon= 720

Step-by-step explanation:

let the total marks obtained be X

from question, Robin = 5X/6

Shaon= 4X/5

then, 5X/6= 4X/5+30

or, 5X/6= 4X+150/5

or 25X=24x+900

or,X= 900

therefore robin=750

Shaon = 720
