12.) she gets 70 because she sells 60 fiction and 20 non fiction and you add 60 to 10 because the things are half off
Answer:
Domain : 0 ≤ x ≤ 8
Range : 5450 ≤ f(x) ≤ 6588.65
Step-by-step explanation:
Expression representing the money Samantha collected after x years is,
f(x) = 
Time 'x' duration for the investment starts from t = 0 and ends at 8 years, so the domain of the given function will be,
Range : 0 ≤ x ≤ 8
Money collected in the fund from 0 to 8 years is,
f(0) =
= $5450
f(8) = 
= $6588.6
Therefore, range of the graphed function will be,
Range : 5450 ≤ f(x) ≤ 6588.65
To find a fraction as a decimal you would divide the denominator by the numerator.
Decimal:
-3/8 = -.375
Then for the percentage you would move the decimal two places to the right.
Percentage:
-37.5 (Since the number to the right isn't a zero we can't drop it) therefore the percentage would be -37.5%
1/7 * 42/1
5 * 42 = 210
7 * 1 = 7
210/7 = 30
30
