Stefan estimates the income and expenses for renting

Elena-2011 [213]

Answer/Step-by-step explanation:

If total income is more than total expenses, she should rent it. If the total income is less than the total expenses, she should not rent it.

Total income estimated in a month:

Sales: $950 per week = 950*4weeks = $3,800 per month

Services: $2,875 per month

Total estimated income per month = $(3,800 + 2,875) = $6,675

Total expenses estimated in a month:

Rent: $4,500 per month

Travel: $7.5 per day = 7.5*7days = $52.5 per week.

Assuming there are 4 weeks in a month, expenses for travel in a month will be:

$52.5*4 = $210

Merchandise: $1,650 per month

Total expenses estimated per month = $(4,500 + 210 + 1,650) = $6,360

Total estimated income ( > total estimated expenses in a month, therefore, Stefan should rent the phone accessory store. She will make profit.

translate phrases into algebraic expressions, the difference between the cube of a number and the square of the number

Korolek [52]

Answer:

$x^3-x^2.$

Step-by-step explanation:

The word "difference" represents a subtraction. Then the algebraic expression will be of the form a-b.

Now, the difference is between the cube of a number and the square of the number, then let's call the number x. The square of the number is raise to two. Then the square of the number is $x^2$ .

The cube of the number is raise to three. Then the cube of the number is $x^3$ .

So, the difference between the cube of a number and the square of the number (we are talking about the same number in the square and the cube) is $x^3-x^2$ .

During a three-day period, a provincial hospital received 24 new patients and discharged 6 on the first day, received 8 and disc

IRINA_888 [86]

Answer:

1 : 3

Step-by-step explanation:

Given the following :

First day :

Patient received = 24

Patient discharged = 6

Second day :

Patient received = 8

Patient discharged = 21

First day :

Patient received = 9

Patient discharged = 6

Number of patient in the hospital at the end of the third day:

Patients received = (24 + 8 + 9) = 41

Patients discharged = (6 + 21 + 6) = 33

Patient received - patient discharged

= (41 - 33) = 8

Number of patients in hospital at the start of the three day period :

Patient received on first day = 24

Patient at the end : patient at the start

8 : 24 = 1 : 3
