On Solving equation in one variable 0.4x = 5.2, we found that the clerk returned 13 dimes, 34 quarters and4 nickels in change of $10 bill.
What is an linear equation in one variable?
Linear equation is an equation containing one variable with power one and constants.
Standard form of an linear equation in one variable x is :
ax + b= 0 , a, b are constants
x= -b/ a is solution if this equation. Linear equation can be solved by adding or subtracting , multiplying , division same number to both sides.
A clerk need a change of $10 bill
Let the clerk returned x dimes and y nickels and z quarters to pay $10
Value of one nickel = $ 0.05, one dime = $ 0, one quarter = $ 0.25
Value of x dimes becomes 0.1x
Value of y nickels becomes 0.05 y
value of z quarters becomes 0.25 z
Total value of given dimes, quarters and nickels , 0.1 x + 0.05 y + 0.25z = 10
Number of dimes = Number of nickels + 9
∴ x = y +9 ⇒ y = x- 9
Number of quarters = Number of dimes +21
∴ z = x + 21
Put y = x-9 and z = x + 21 in 0.1 x + 0.05 y + 0.25z = 10
Then,
0.1 x + 0.05 ( x-9) + 0.25 (x +21) = 10
⇒ 0.1 x +0.05x -0.45 + 0.25 x + 5.25 = 10
⇒ 0.4x +4.8 = 10
⇒ 0.4 x = 10- 4.8
⇒ 0.4x = 5.2
⇒ x = 5.2/0.4 = 13
Thus , y = x-9 = 13 -9 = 4
z = x + 21 = 13 + 21 = 34
Therefore, the clerk returned 13 dimes , 4 nickels and 34 quarters for $10 bill.

dimes. 13×0.10= 1.30
Nickels. 4×0.05= 0.20
total=10.00
(21×0.25)+(9×0.10)+(4×0.05)+(4×0.10)+(13×0.25)=10

No, because the light bulb distributor trusts the LED bulb manufacturer.
Yes, because the LED bulb manufacturer may benefit from the survey results.
Yes, because the light bulb distributor wants to become a "green" company.
Answers
Answer:
C. Yes, because the LED bulb manufacturer may benefit from the survey results.
Step-by-step explanation:
We are given that,
'An LED bulb manufacturer gives the study with the result that LED light bulbs are better for the environment than the traditional bulbs'.
Now, if the light bulb distributor further shows the result to the consumers, they would like to buy LED bulbs.
So, the demand for the LED bulbs would increase. For that, the distributor would have to order more LED bulbs from the manufacturer.
Thus, the supply of LED bulbs would increase for the manufacturer resulting in increase in revenue.
Hence, the LED manufacturer may benefit from the survey result.
Yes, because the LED bulb manufacturer may benefit from the survey results.
If the light bulb distributor will decide get more stock of LED bulb due to the study given by the LED company, then, the LED company will benefit from it.
