the correct question is
Compute the total cost per year of the following pair of expenses. Then complete the sentence: On an annual basis, the first set of expenses is _% of the second set of expenses.Sheryl spends $17 every week on cigarettes and spends $24 a month on dry cleaning.
we know that
1 year is equal to 52 weeks
1 year is equal to 12 months
To calculate:
$17 * 52 = $884
$24 * 12 = $288
then
884/288 = 3.0694
* 100 = 306.94%

Answer:
0.55A dollars
Step-by-step explanation:
If 45% of the money was spent, then the percentage left was
100% - 45%, or 55%.
Thus, to answer this question, we multiply (A dollars) by 0.55:
0.55A dollars was left after the expenditure of 45% of the original amount.
This year there are 900 rabbits which represents 200% of last year's population, means that last year the number of rabbits was:
x = 900 (100/200) = 450 rabbits.
The mathematical expression can be derived by a simple rule of three.
So, for last year the population was 450 rabbits.
To find the intercept of a variable in a equation with more than one variable, you need to equal the others variables to zero.
-> 4x -6y -5z = 60
-> X-Intercept:
To find the X intercept, equal the Y and Z values to 0.
(Y = 0; Z = 0)
4x -6(0) -5(0) = 60
4x = 60
x = 60/4
x = 15
-> Y-Intercept:
To the Y intercept it's the same thing, equal the another variable values to 0.
(X = 0; Z = 0)
4(0) -6y -5(0) = 60
-6y = 60
-y = 60/6
-y = 10 x(-1)
y = -10
-> Z-Intercept:
(X = 0; Y = 0)
4(0) -6(0) -5z = 60
-5z =60
-z = 60/5
-z = 12 x(-1)
z = -12
Answer: The intercepts for this equation (15,-10,-12).
Or: x = 15, y = -10, z = -12.
