Answer:
f(x) = 0.5x + 5
Domain: positive whole numbers
Range: f(x) ≥ 5
Step-by-step explanation:
Let's x denote the total number of fruit juice.
This means that if $0.5 for each fruit juice, then the total cost incurred for fruit juice would be $0.5x.
Since she incurred a cost of $5 for 100 cups and $0.5 for each fruit juice, then the total cost, f(x), would be:
f(x) = 0.5x + 5
The domain would be all positive whole numbers (it is restricted to positive whole numbers because a fruit juice can't be "negative" neither can it be "half").
The range is all numbers equal or greater than 5. This is because, even if she does not eventually get fruit juice, she will still incur a cost of 5usd for cups.
The equation of this line would be: y= x +4
Answer:
On Blue print 18 centimeters represents <u>3.6 meters</u>.
Step-by-step explanation:
Given:
Scale is 10 cm = 2 m
We need to find the number of actual meters are represented by 18 1818 centimeters on the blue print.
Solution:
Now we know that;
10 cm = 2 m
so 1 cm = Number of meters in 1 cm.
By using Unitary method we get;
Number of meters in 1 cm = 
Now we know that;
1 cm = 0.2 m
18 cm = Number of meters in 18 cm.
Again by using Unitary method we get;
Number of meters in 18 cm = 
Hence On Blue print 18 centimeters represents <u>3.6 meters</u>.
Let student tickets are x and adult tickets are y
x + y = 516.........x = 516 - y .........(substitute in 2)
3x + 5y = 2046 ......(2)
3(516-y) + 5y = 2046
1548 - 3y + 5y = 2046
2y = 498
y = 249
x = 516 - y = 516 - 249 = 267
so the correct answer is b
