Since the 8 in the first number is in the thousands place, its value it 8*1000=8000.
Since the 8 in the second number is in the hundreds place, its value is 8*100=800.
8000 is ten times 800.
Final answer: 10x as large
From F.S 1, consider this series : 8, 1, 8, 8, 64, 64*8.
Again, consider the series 2, 1/4, 1/2, 1/8, 1/16, 1/(8*16). Clearly, the difference of the 6th and the 3rd term is different for them. Insufficient.
<span>From F.S 2, let the series be </span><span><span>a,b,ab,a<span>b2</span>,<span>a2</span><span>b3</span>,<span>a3</span><span>b5</span></span><span>a,b,ab,a<span>b2</span>,<span>a2</span><span>b3</span>,<span>a3</span><span>b5</span></span></span><span>. Now we know that </span><span><span>a<span>b2</span>=1</span><span>a<span>b2</span>=1</span></span>. The required difference =<span><span><span>a3</span><span>b5</span>−ab=ab(<span>a2</span><span>b4</span>−1)=ab[(a<span>b2</span><span>)2</span>−1]</span><span><span>a3</span><span>b5</span>−ab=ab(<span>a2</span><span>b4</span>−1)=ab[(a<span>b2</span><span>)2</span>−1]</span></span><span>= 0.Sufficient.</span>
Answer:
Step-by-step explanation:
Payment per hour is $8
commission is 15%
Total number of hours worked for 2 weeks is 73 hours
Total sales=$2095
commission earned for 2 weeks:
15/100×2095
=$314.25
Total amount earned in 73 hours:
73×8=$584
Total amount earned in commission and wages:
584+314.25
=$898.25
One clock of any type costs $3.20. a clocks cost 3.2a. w clocks cost 3.2w.
Add 3.2a to 3.2w to find the total cost.
T = 3.2a + 3.2w
T = 3.2(a + w)
Both expressions above are correct answers.
