Answer: f(3.5) = 58.20
Step-by-step explanation:
Wow...what degree of exponent are we to assume?
I'll go with 2 as we are only given two exemplars.
f(x) = x² + Ax + B
f(- 2.5) = 9 = (-2.5)² + (-2.5)A + B
f(2.5) = 45 = (2.5)² + (2.5)A + B
we can subtract the first equation from the second
45 - 9 = 2.5² - (-2.5)² + 2.5A - (-2.5A) + B - B
36 = 5A
A = 7.2
45 = (2.5)² + (2.5)7.2 + B
B = 20.75
F(3.5) = 3.5² + 7.2(3.5) + 20.75 = 58.2
Answer:
13 cents
Step-by-step explanation:
$49.80 is INCLUDING tax of $1.92. So the cost before tax is:
49.8 - 1.92 = $47.88
This is the price of FOUR bottles. So price PER BOTTLE is:
47.88/4 = $11.97
This $11.97 is a 95 ounce bottle.
We need to find price PER OUNCE, so we divide the price by 95:
11.97/95 = $0.126 PER OUNCE
Rounded to 2 decimal, that would be around $0.13 per ounce
Raj earned 58 and spent 42, so he saved 58-42 = 16.
Michael earned 83 and saved 20, so he spent 63, but that doesn't matter.
for Raj, 100% of his earning is 58, how much is 16 off of it as a percentage?
for Michael, 100% of his earnings is 83, how much is 20 off of it as a percentage?
and you can see clearly which percentage is higher.
