Answer:
Net profit= $156,354
Step-by-step explanation:
Giving the following information:
A furniture company sells a desk for $1,435. It cost the company $817 to make the desk. Last month, 253 desks were sold.
<u>To calculate the net profit, we need to use the following formula:</u>
Net profit= number of units sold*(selling price - unitary cost)
Net profit= 253*(1,435 - 817)
Net profit= $156,354
34-13.6=20.4
20.4/34= .60
60% off
Answer: 40 stamps
Step-by-step explanation:
Let Maddy = M and Simon = S
Given that maddy had twice as many stamps as simon. That is,
M = 2S ....(1)
After maddy sold 60 stamps, simon had twice as many stamps as maddy. That is,
S = 2( M - 60) .... (2)
Substitutes M for 2S from equation (1) into equation (2)
S = 2( 2S - 60 )
Open the bracket
S = 4S - 120
Collect the like terms
S - 4S = -120
- 3S = - 120
S = 120/3
S = 40
Substitute S into the equation (1)
M = 2 × 40 = 80
Maddy has 80 - 40 = 40 stamp
Therefore, Maddy has 40 more stamps than simon in the beginning.
50-n is the answer although you could use a different variable.
