Answer:
i) Total Profit = ₹ 33,000
ii) Number of White Cement bags company has to sell = 3000
Step-by-step explanation:
Let
Total number of white cement bags = x
Total number of grey cement bags = y
Profit for White Cement = ₹ 9 / bag
Profit for x number of white cement bags = 9x
As "LOSS" can also be written as "- PROFIT"
Profit for Grey Cement = -₹ 5 / bag
Profit for y number of Grey cement bags = -5y
Total Profit = 9x - 5y
(If value of Total Profit is negative, it is a Loss)
<h3>
Part (i)</h3>
x = 7000
y = 6000
Total Profit = 9x - 5y
Total Profit = 9(7000) - 5(6000)
Total Profit = ₹ 33,000
<h3>Part (ii)</h3>
y = 5400
Total Profit = 0
Total Profit = 9x - 5y
0 = 9x - 5(5400)
9x = 5(5400)
x = 5(54000/9
x = 3000 bags

Answer:
Pablo decides to save his money in a piggy bank and each day he saves $ 100 more than the day before. How much would he save on day "20" if he had $ 100 on the first day? Express the function and solve
Step-by-step explanation:
A. Alright, we want to multiply one equation by a constant to make it cancel out with the second. Since the first equation has a "blank" y, let's multiply the first equation by <em>2</em>.
3x-y=0 → 2(3x-y=0) = 6x - 2y = 0
5x+2y=22
The answer for this part would be: 6x - 2y = 0 and 5x + 2y = 22
B. So now we combine them:
6x - 2y = 0
+ + +
5x + 2y = 22
= = =
11x + 0 = 22 ← The answer
C. Now that we have the equation 11x = 22, we solve for x
11x = 22 ← Divide both sides by 11
x = 2 ← The answer
D. Now that we have x=2, we plug that back in to 5x+2y=22 and solve for y:
5(2)+2y = 22
10 + 2y = 22
2y = 12
y = 6
<u>Therefore, the solution to this problem is x = 2 and y = 6</u>
