Answer:
The college student can spend <u>$15.00</u> in December.
Step-by-step explanation:
This can be calculated as follows:
Let y represents the amount to spend in December.
The can now us the formula for calculating a mean is as follows:
Mean = Sum of montlhy spending / Number of months ...... (1)
From the question, we have:
Mean = $50
Sum of monthly spending = $100 + $25 + $80 + $30 + y = $235 + y
Number of months = 5
Substituting the values into equation (1) and solve for y, we have:
$50 = ($235 + y) / 5
$50 * 5 = $235 + y
$250 = $235 + y
$250 - $235 = y
$15.00 = y
Therefore, the college student can spend <u>$15.00</u> in December.

Answer:
64.468
Step-by-step explanation:
y varies directly with x.
The constant of variation is k = 7
Step-by-step explanation:
We have to check whether both vary directly with each other or not.
Every pair of x and y will be considered one by one
If y varies directly with x, it should satisfy y = kx or k = yx
So,
For x= -2, y=-14
For
x=3, y=21
For
x=5, y=35
As k is same for all pairs of x and y, it can be concluded that:
y varies directly with x.
The constant of variation is k = 7
