600 sixth-graders were surveyed.
Step-by-step explanation:
Step 1; Assume x is the total number of sixth-graders that were surveyed. According to the given circle graph, 5% of the sixth-graders that were surveyed have birds as their pets. If x is the total number of sixth-graders surveyed then 5% of x equals 30. So
5% of x = 30.
5% equals = 0.05, so 5% = 0.05.
Step 2; If 0.05 x = 30, we can solve by keeping the unknown value on one side and keeping all the known values on one side.
x = = 600.
So 600 sixth-graders were surveyed.
The answer is C 24 0.5- liter bottles for 5.25
First, add up how many full liters are in each answer
a - 2 liters
b - 3 liters (3 + 1 = 3)
c- 12 liters (24 x 0.5 = 12)
d - 9 liters (36 x 0.25 = 9)
So now you know how many liters of water you’re getting for what price which is
a. 2 liters for .89
b. 3 liters for 1.50
c. 12 liters for 5.25
d. 9 liters for 4.75
Now, you must divide the price by how many liters you’re getting to know how much each liter cost by itself.
a- .89 divided by 2 = .45 cents a liter
b- 1.50 divided by 3 = .50 cents a liter
c- 5.25 divided by 12 = about .44 cents a liter
d- 4.75 divided by 9 = -about .52 cents a liter
So by the information, the cheapest and best deal would be answer C because it cost the least for 1 liter (.44 cents)

The LEAST selling price of the laptop should be ;
$1024.1 in other to avoid loss.
Price of laptop = $770
Tax = 20%
VAT = 13%
TO avoid loss ; both the VAT percentage and TAX must be added to the price of the laptop:
Total percentage = VAT + TAX = (20 + 13) = 33%
THEREFORE, Least selling price should be :
Price of laptop * (1 + 33%)
770 * 1.33
= $1024.1
