Answer:
x=11/2
Step-by-step explanation:
We need to separate his total earnings out into the different categories:
Category 1 (2%): 30,000
Category 2 (3%): 60,000-30,000 = 30,000
Category 3 (5%): 92,000-60,000 = 32,000
To calculate a percentage we multiply by that percentage divided by 100.
Now we can work out the commissions:
1) 30,000*0.02 = $600
2) 30,000*0.03 = $900
3) 32,000*0.05 = $1600
Adding these together, we get $3100
9x +1= 0
9x/9 +1-1=0
X= 9-1
X= 8
Answer: length = 30, breadth = 15
length = l
breadth = b
l = 2b
2b + b + 2b + b = 90
6b = 90
b = 15
l = 2b
l = 2(15)
length = 30
b = 15
breadth = 15
