Answer:
c = 31.5
Step-by-step explanation:
Given c varies directly as 
then the equation relating them is
c = k ← k is the constant of variation
To find k use the condition c = 14 when d = 64, then
14 = k ×
= 8k ( divide both sides by 8 )
1.75 = k
c = 1.75 ← equation of variation
When d = 324 , then
c = 1.75 × 
= 1.75 × 18 = 31.5
Third one I think 10,20,30,40
The correct option is C.
The difference of a number and 7 is 21 implies that
n - 7 = 21
To solve for n,
n - 7 = 21
n = 21 + 7 = 28
Therefore, n = 28.
