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:
Question:
Jackson buys a grape snow cone on a hot day. By the time he eats all the "snow" off the top, the paper cone is filled with 27\pi27π27, pi cm^3 3 start superscript, 3, end superscript of melted purple liquid. The radius of the cone is 333 cm. What is the height of the cone?
Answer:
The height of the cone is
Explanation:
It is given that the radius of the cone is
The volume of the cone is
The height of the cone can be determine using the formula,
Substituting the values and
, we get,
Multiplying both sides by 3, we have,
Dividing both sides by , we have,
Thus, the height of the cone is
Step 1: 198 × = 66, the number of men who left the party
Step 2: 256×= 64, the number of women who left the party
66+64=130
Since 130 is the number of people that left, you would subtract it from the total number of people at the party originally.
198+256=454
454-130=325
So, 325 people are left at the party
