a school bake sale earned over $25 from selling cookies, which cost $3 each. how many cookies did they sell? identify the number

SSSSS [86.1K]

It said the sale earned OVER $25 from selling cookies at $3 dollars each so if we let r=revenue , p=price per cookie and c=number of cookies sold:

pc>r and since p=3 and r=25

3c>25 divide both sides by 3

c>25/3

Since cookies are quantized units, they must be integers so:

c>8 1/3

c≥9 or in interval notation

c=[9, +oo)

The product of some negative number and 4 less than twice that number is 286 find the number

Naya [18.7K]

Let's say that number is hmmm "a"

now.. twice "a" is 2*a or 2a
4 less than that is " 2a - 4"

now, the product of those two fellows is 286, well ok

a( 2a - 4) = 286

thus

$\bf a(2a-4)=286\implies 2a^2-4a^2=286\implies a^2-2a^2=143
\\\\\\
a^2-2a^2-143=0\implies (a-13)(a+11)=0
\\\\\\
\begin{cases}
a-13=0\implies &a=13\\
a+11=0\implies &\boxed{a=-11}
\end{cases}$
