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

62.5%
2x/5 - X/2 = 40
LCD = 10
2•(2x/5) - 5•(X/2) = 40
4x/10 - 5x/10 = 40
4x-5x/10 = 40
-X/10 = 40
10•(-X/10) = 40 • 10
-X = 400
-X/-1 = 400/-1
X = -400.
I believe the solution is that X = -400.
Answer:
8
Step-by-step explanation:
When flipping a coin, you get a head (H) or a tail (T)
The second part of the tree diagram will be HT HT
The third part of the tree diagram will be HT HT HT HT
The outcomes are 8
H-------H---------H---------HHH
T-------- HHT
T----------H----------HTH
T---------HTT
T-------H-----------H---------THH
T---------THT
T------------H--------TTH
T--------TTT
15 + .65x = 80
15 + .65x = 80
15 - 15 + .65x = 80 - 15
.65/.65x = 65/.65
x = 100
