Answer:
Step-by-step explanation:
From the law if variation,
x <> y ______(1) ,where <> is known as the constant if proportionality.
x = k/y where k is a constant____(2)
Substitute for the values of x and y to get the k
9 = k/6
Therefore k= 54
To find the value of x, go back to equation 2 and substitute for the values if k and y given and computed.
x = 54/15; reduced to lowest term
x = 18/5
x = 3.6
Answer:
There are 39 people in the Filmmaking club and 25 in the Yearbook Club

I really hope this is right, it was kinda confusing! Sorry if I got it wrong!!
Answer: R12.20
Step-by-step explanation:
VAT in South Africa is 15% so if the flat rate is R93.57, the VAT amount can be found by finding the pre-tax flat rate:
93.57 = x + 0.15x
1.15x = 93.57
x = 93.57/1.15
x = R81.37
VAT is 15% of R81.37:
= 15% * 81.37
= R12.20
