Answer 1

1.c.You have more credits than debits.

2.d.$38.00

3.d.$220.50

Explanation:

Being in blacks in accountability is often referred when a person or institution has a profit or positivie numbers after a fiscal period, in this case it means having more credits than debit, or owning more than you own.

To calculate this you just have to add up all of her expenses:

8.70+7.35+16+5.95=38

So the total for the expenses of the week is $38

To calculate her earnings we just have to calculate first the money she earned in her part time job, multiplying the number of hours she worked by the amount of money she makes per hour:

18*7.25=130.5

And now we add the money she made for the walking of the dogs, in total she walked 6 dogs for half an hour and 2 dogs for an hour, tha makes a total of 10 half hours, so we multiply that by the $9 she makes per half an hour and the total is 90.

So she earned $90 from walking the dogs, and 130.5 from her part time job, for a total of 220.5

Ques 2)

The expenses of Belinda are as follows:

Bus fare ---- $8.70

Lunch out ---- $7.35

Hair cut------ $16

Movie rental---- $5.95

Hence the total expenses are calculated as:

$ 8.70+$ 7.35+$ 16+$ 5.95

=$ 38.00

Ques 3)

Niah earns $7.25 per hour at her part-time job that she works at 18 hours per week.

Hence, the total amount she earns at her part-time job is:

$ (18×7.25)=$ 130.5

Also, Niah’s friend pays her $9 per dog for each half hour walked.

• Monday: 3 dogs for 0.5 hours

Amount she earn on Monday is:

3×9=$ 27

• Wednesday: 2 dogs for 0.5 hours and 1 dog for 0.5 hours

Amount she earn on Wednesday is:

2×9+9=$ 27

• Thursday: 2 dogs for 1 hour

Amount she earn on Thursday is:

2×9+9×2=$ 36

Hence, the total amount Niah earns from dog walking service is:

$ (27+27+36)=$ 90

Hence, the total earning of Niah this week is:

$ (130.5+90)= $ 220.50
