Equation 2.
length=3w, new length=2+3w, new width=1+w
New Perimeter=62=2(new length+new width)
62=2(2+3w+1+w) => 62=2(3+4w)
-4w + 8v + 2y = -4w + 8v + 2y
Answer:1. B 2. D
Step-by-step explanation:
Answer: her sales for the month of May is $55000
Step-by-step explanation:
Let x represent her total sales for the month of May.
Each month she receives a 5% commission on all her sales of medical supplies up to $20,000. This means that for her first sales worth $20000, she earns a commission of
5/100 × 20000 = 1000
She also earns 8.5% on her total sales over $20,000. This means that for sales over $20000, she earns
8.5/100(x - 20000) = 0.085x - 1700
Her total commission for May was $3,975. The expression becomes
1000 + 0.085x - 1700 = 3975
0.085x = 3975 + 1700 - 1000
0.085x = 4675
x = 4675/0.085
x = 55000
2.8. The mean of the problem was 10. After subtracting each number by 10 I added the absolute value of each difference. I divided that sum by 5 and got 2.8
