Answer:
For instance, say you pay $8,000 for goods and sell them for $10,000. Your gross profit is $2,000. Divide this figure by the total revenue to get your gross profit margin: 0.2. Multiply this figure by 100 to get your gross profit margin percentage: 20 percent.
Step-by-step explanation:
Answer:
9/20 or .45
Step-by-step explanation:
3/4 x 3/5 = .45 or 9/20
So 5+x=47
subtract 5 from both sides
x=42
not 52
the answer is 42
Answer:
24
Step-by-step explanation:
4a+2b= 86 cm
a²+b²= 386 cm²
a+b=?
----------
- 4a+2b= 86
- 2a+b= 43
- (2a+b)²=43²
- 4a²+4ab+b²=1849
b²= 386- a², b= 43- 2a
- 4a²+4a(43-2a)+386-a²-1849=0
- 4a²+172a-8a²-a²-1463=0
- -5a²+172a-1463=0
- 5a²-172a+1463=0
solving quadratic equation we get
a=19 - integer solution
b= 43-2*19= 5
a+b=19+5=24
