the answer is C a=3 for this equation
Answer:
a. 2n = 3n − 12, 12
Step-by-step explanation:
Let the number be represented by n.
Then 2 times the number is 2*n = 2n
3 times the number = 3*n = 3n
12 minus 3 times the number is 3n-12
It is given that 2 times the number is the same as 12 minus 3 times the number.
Expressing this equation form:
![\[2n=3n-12\]](https://tex.z-dn.net/?f=%5C%5B2n%3D3n-12%5C%5D)
Solving the equation,
![\[3n-2n=12\]](https://tex.z-dn.net/?f=%5C%5B3n-2n%3D12%5C%5D)
![\[=> n=12\]](https://tex.z-dn.net/?f=%5C%5B%3D%3E%20n%3D12%5C%5D)
Hence the required number is 12.

Answer:
the cost of making each paperweight = $0.81
Step-by-step explanation:
First let us calculate the selling price for each paperweight as follows:
total amount gotten = $230.85
number of paperweights = 95
∴ 95 paperweights = $230.85
∴ 1 paperweight = 230.85 ÷ 95 = $2.43
selling price of 1 paperweight = $2.43
Next, let the cost of making 1 paperweight be 'x'
selling price of paperweight = cost of making + profit gotten
The cost of making the paper weight (x) plus the profit made on the paper weight (2x) equals the selling price of each paper weight.
x + 2x = 2.43 (the profit the club makes is two times as much as the cost to make each paperweight)
∴ 3x = 2.43
x = 2.43 ÷ 3 = 0.81
Therefore, the cost of making each paperweight = $0.81
