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.
House price = down payment + mortgage x number of months
430,000 = 250,000 + 2,000x where x is number of months
To find number or months solve for x
430,000 = 250,000 + 2,000x
Subtract 250,000
180,000 = 2,000x
Divide by 2,000
x = 90 months
12 months in one year
90 = 84 + 6 = 12 x 7 + 6
7 years and 6 months
