Answer:
45
Step-by-step explanation:
Let us assume the Bags of oranges be x
Now the cost price is 2500x
Sale price N = 90,000
Loss =20%
As we know that
Cost price= selling price × 100/ 100-percentage loss
= 90,000 × 100/ 100- 20
= 90,000 × 100 /80
Cost price= 112,500
Now
The Number of bags of oranges is
= 112,500 ÷ 2500
= 45
Answer:
p = 497 ( to the nearest whole number)
Step-by-step explanation:
In order to do this calculation, we will apply the principle of accounting, where a certain amount is compounded periodically and yielding a future value. Compound interest is used because the percentage growth rate is added on the new amount gotten each year, and not on the first or original amount.
Hence:
FV = PV × 
where FV = future value = population in 2020 = 810
PV = present value = population in 2010 = p
r = percentage growth rate in decimal = 5% = 5/100 = 0.05
n = growth rate period per year = once = 1
t = time in years = 2010 to 2020 = 10 years
∴ 
(dividing both sides by 1.6289)
p = 810 ÷ 1.6289 = 497.2 = 497 (to the nearest whole number)
∴ population in 2010 = 497
Answer:
y = x - 8
Step-by-step explanation:
y = x - 8
Check your answer using (0, -8):
y = x - 8
-8 = 0 - 8
-8 = -8
This statement is true

Answer:
<u>The correct answer is A. Divide both sides by positive 5</u>
Step-by-step explanation:
Let's solve the equation for finding z and the necessary steps to do it:
5z - 3 = 12
5z = 12 + 3 (Adding 3 at the right side and subtracting 3 at the left side)
5z = 15 (Adding 12 plus 3 at the right side)
5z/5 = 15/5 (Dividing by positive 5 at both sides)
<u>z = 3</u>
<u>The correct answer is A. Divide both sides by positive 5</u>
