Ameen went to the salon and had 3/8 of an inch of hair cut off. The next day she went back and asked for another 1/2 of an inch
GaryK [48]

Answer:

Total hair cut off  = \frac{7}{8}

Step-by-step explanation:

Given - Ameen went to the salon and had \frac{3}{8} of an inch of hair cut off. The next day she went back and asked for another \frac{1}{2} of an inch to be cut off.

To find - How much hair did she have cut off in all?

Proof -

Given that,

Firstly,

She cut off her hair = \frac{3}{8}

Then,

She cut off her hair = \frac{1}{2}

So,

Total hair cut off = \frac{3}{8} + \frac{1}{2}

                           = \frac{3 + 4}{8} = \frac{7}{8}

⇒Total hair cut off  = \frac{7}{8}

Imagine you have a job where you earn $700 each week after taxes. Your monthly living expenses include $725 for rent, $125 for u
Softa [21]

The monthly income is $844.

Given:

  • Weekly earning after taxes is $700
  • Monthly rent is $725
  • Monthly expense for utilities is $125
  • Monthly expense for cable/internet is $120
  • Monthly expense for cellphone is $35
  • Monthly expense for bus fare is $48
  • Minimum monthly payment of credit card debt is $78
  • Monthly expense for groceries is $600
  • Monthly expense for dining out and entertainment is $225

To find: The monthly income

The monthly income refers to the amount of money left over each month after paying all expenses.

Evaluating, we have,

The total monthly expense = $(725 + 125 + 120 + 35 + 48 + 78 + 600 + 225)

That is, the total monthly expense is $1956.

It is given that weekly earning after taxes is $700. Since a month contains 4 weeks, we can say that monthly earning after taxes is $(700 \times 4), that is, $2800.

Then, monthly income is given by the difference between the monthly earnings and the monthly expenses. So, monthly income is $(2800-1956), that is, $844.

The monthly income is $844.
