Answer:
C) 0.066...
Step-by-step explanation:
1/15 = 0.066...
You could eliminate B and C as 15 (numerator from question) is not a multiple of 10. You can eliminate A as the numerator of 15 from the question is larger than 10 and will result in a number less than 0.1.
To better understand the problem see the attached figure
we have
Multiply by 
both sides
Group terms that contain the same variable p and move the constant to the other side of the equation
Step-by-step explanation:
3.25÷2=1.625
19.5÷1.625=12
R = 16 according to the problem, so the total amount of income will be:
$20*16 + $15*(40 - 16)
= $320 + <span>$15*(24)
= </span>$320 + <span>$360
= $680
that is the income, but the expenses are $275 so the total revenue is the subtraction of those two
total revenue = $680 - $275
= $405</span>
