4 bags of cement do 18 m² how many m^2 can be done with seven bags

Mathematics
1 answer:
nikitadnepr [17]2 years ago
5 0

Answer:

31.5 m^2

Step-by-step explanation:

To find the amount for 7 bags, create a proportion.

\frac{4}{18} =\frac{7}{y}

To solve for y, cross multiply numerator to denominator of each fraction.

4(y) = 18(7)

4y= 126

y= 31.5

7 bags will do 31.5 m^2

A study on how circus ticket pricing influences ticket sales shows that there is an average increase of 4 people for every $3 de
____ [38]
Let the price of a ticket be originally T dollars, and the number of clients be N.

let the price decrease by x  3-dollars.

"there is an average increase of 4 people for every $3 decrease on the price of the ticket."

means:

if the price is decreased by 1-3$:
 then N become N+4, and T becomes T-3    


if the price is decreased by 2-3$:
 then N become N+4+4=N+2*4, and T becomes T-3-3=T-2*3    

 So if the price is decrease by x-3 dollars:

N  becomes N+4x, and T becomes T-3x


"A circus owner sells an average of 340 tickets when the price of a ticket is $75."

In this case N=340, and T=75$

If the owner does not change the price ticket, x=0, the revenue is 340*75,

If the owner decreases the price of the tickets by x-3$, then the revenue will be 
(N+4x)(T-3x)=(340+4x)(75-3x) dollars,

If R is the function of the revenue depending on x, then 

R(x)=(340+4x)(75-3x) dollars

 
Answer: R(x)=(340+4x)(75-3x) dollars
