Edurado started a business selling sporting goods.He spent $ 7500 to obtain hos merchandise , and it cost him $300 per week for

Alik [6]

Answer:

C) It will take 14 weeks for Edurado to make a profit.

Step-by-step explanation:

The money spent on obtaining the merchandise = $ 7500

The general expense per week = $300

Let us assume Eduardo has to work for N weeks to break Even.

So, the general expense in N weeks = N x( Expense per week)

= N x ( $300) = 300 N

So, the total expense in N weeks = Money spent on merchandise + general expense

or, the TOTAL EXPENSE = $ 7500 + 300 N .... (1)

Now, the earning per week = $850

So, the total earning in N weeks = N x ( Earning in 1 week) = N x ( $850)

or, the TOTAL EARNING = 850 N .... (2)

Now, for N weeks ,

TOTAL EXPENSE = TOTAL EARNING

⇒ $7500 + 300 N = 850 N

or, 7500 = 850 N - 300 N = 550 N

⇒ N = 7500/550 = 13.63

So, number of weeks should at least be 13.63

Among the given options, N = 14 weeks is the most feasible answer.

Hence, it will take 14 weeks for Edurado to make a profit.

It's easy it's called Two-way tables please help

Vesnalui [34]

Answer: The filled out table is shown below in the attached image

===========================================================

Explanation:

The letters A through J are one way to fill out the table. Though there are other possible orders.

Start at letter A, which is from the fact we have 40 people total

Then move to letter B. This is the total number who like pasta (26)

We have C = A-B = 40-26 = 14 people who don't like pasta

--------------

Now move to cell D. This is the total who don't like netball, which is 21 people. There are E = A-D = 40-21 = 19 people who do like netball.

F = 4 is the number of people who don't like either thing (netball or pasta). So G = D-F = 21-4 = 17 people like pasta but don't like netball.

Of those people who like netball (E = 19), we have 9 who also like pasta. This is in cell H in the upper left corner. This means J = E-H = 19-9 = 10 people like netball but don't like pasta.

----------------

So we have these values

A = 40
B = 26
C = 14
D = 21
E = 19
F = 4
G = 17
H = 9
J = 10
