Amy wants to sell at most 25 cookies and at least 10 sprites
per day. she profits $.50 on every cookie and $1.00 on every
sprite. she wants to earn at least $ 30 per day. which of the
following systems of inequalities represents this scenario?
a. x + x 225
b. xs 25
.50x + y 2 30
y? 10
x + y 230
c. x < 25
y 2 10
.50x + y 2 30
d. x < 25
y> 10
.50x + y > 30

Step-by-step explanation:

It is given that,

Amy wants to sell at most 25 cookies ,

Let number of cookies be '' , then should be less than or equal to 25

Which is represented by  ,

Further,

Let number of sprites be '', then '' should be greater than or equal to  10

Which is represented by

Also,

Given,

she profits $.50 on every cookie

and $1.00 on every  sprite.

So total profit on selling cookies would be

= Profit on each cookie times the number of cookies

=

=

Similarly, total profit on selling sprites would be

=profit on each sprite times the number of sprites

=

=

Now, combining these two should be greater than or equal to $30

representing this through an equation,

Thus the sysytem of equations is given as:

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
