In an answer the exponent can't be negative
Answer:
M = 6.50n
Step-by-step explanation:
since it is per child, it will be multiplied by the amount of children, n. Therefore giving us the cost of M, or the equivalent.
We can factorise this expression by grouping. First let us arrange it in this way
Let us bracket them like this:
In the first bracket portion, take x as common and in the second expression, take 2 as common.

Answer:
k = 42
the constant of proportionality in this inverse variation is 42.
Step-by-step explanation:
Let x represent the number of people that want cake
And y the number of slices each can have;
Since x is inversely proportional to y;
x = k/y .....1
Where k is the proportionality constant;
To solve for k, we will substitute any of the case scenario given into equation 1.
If 14 people want cake, then they can each have 3 slices;
x = 14 , y = 3
substituting;
14 = k/3
k = 14 × 3 = 42
k = 42
the constant of proportionality in this inverse variation is 42.
Therefore,
x = 42/y
