The break even point will be "(520, 36670.4)".

Given that:

Cost function,

  • y = 25.42x + 23452

Revenue function,

  • y=70.52x

We know that, at break even:

→ Cost \ price = Revenue \ price

Now,

→ 70.52x=25.42x + 23452

By substracting "25.42x" from both sides, we get

→ 70.52x-25.42x=25.42x + 23452-25.42 x

→                 45.1 x = 23452

→                        x = \frac{23452}{45.1}

→                           = 520

then,

→ y = 70.52x

→    = 70.52\times 520

→    = 36670.4

Thus the answer above is correct.

A= 1.142 m/hr

Width of beach at 8 p.m. = 36 m

Width of beach at 3 a.m. = (36-8) m =28 m

Average change in width(A) = change in width (Width of beach at 8 p.m.-Width of beach at 3 a.m.0/ time in hours

A= ( 36-28)/ 7

A= 8/7 m/hr

three adults and four children must pay $122 for tickets. Two adults and three children must pay $87. what are the price of each
Natasha2012 [34]

Let a be the price of an adult ticket, and c the price of a child ticket.

The sentence "Three adults and four children must pay $122 for tickets" translates to 3a+4c = 122

The sentence "Two adults and three children must pay $87" translates to 2a+3c = 87

Which leads to the linear system

\begin{cases} 3a+4c = 122\\2a+3c = 87 \end{cases}

You can solve this system as you prefer, for example you can multiply the first equation by 2 and the second by 3 to get

\begin{cases} 6a+8c = 244\\6a+9c = 261\end{cases}

Now subtract the first from the second:

(6a+9c) - (6a+8c) = 261-244 \iff c = 17

Now plug this value for c in any of the equations, for example the first:

3a+4c = 122 \iff 3a+4\cdot 17 = 122 \iff 3a+ 68=122 \iff 3a = 54 \iff a = 18

Hannah finds purple, blue, and silver space rocks while exploring.
Lisa [10]

Answer:

She has 15 more purple rocks than blue.

Step-by-step explanation:

purple= 2/3 of all rocks

blue= 3/4 of all rocks that aren't purple

silver= 3 (or 1/4 of all rocks that aren't purple)

if 3 (silver) is 1/4 of all rocks that aren't purple, blue (3/4) is 3x3=9

if purple is 2/3 of all rocks, blue and silver are 1/3 of all rocks

so 1/3 of all rocks would be 9+3=12

if 1/3=12, then 2/3 (purple)=24

-----

At this point:

purple=24

blue=9

silver=3

-----

purple (24) - blue (9) =15

She has 15 more purple rocks than she does blue.
