Answer:
483.75 is needed
Step-by-step explanation:
161.25 * 4 = 645.00
645.00 - 161.25 =
6 times 10 is 60. 60 plus 5 is 65.
Answer:
Part A) the direct variation equation that relates x and y is:

Part B) value of y = 75
Step-by-step explanation:
Part A)
We are given that y varies directly with x, and y=10 when x=-2 what direct variation equation relates x and y?
If x and y are directly related then:
y ∝ x or y=kx
where k is constant of proportionality.
Now, finding k:
y=10 and x=-2

So, value of k = -5
So, the direct variation equation that relates x and y is:

Part B)
What is the value of y when x = -15
the equation is:

Putting x = -15

So, value of y = 75
