Selling Price = $820
Mark up = 25% Cost Price
Selling Price = Cost Price + 25% Cost Price.
Let the cost price = x
Selling Price = x + 25% of x
820 = x + 0.25x
820 = 1.25x
820/1.25 = x
656 = x
Dealer's Cost of refrigeratior = $656
The rule for this arithmetic sequence is you multiply 1.2
Then you will keep multiplying 1.2 until you get to 2012 and you should get 82,413.1584 as your final answer!
Answer:
Answer: So, the possible numbers that when rounded to the nearest hundred are 12000 are from 11500 to 12049
Step-by-step explanation:
Answer: 15m
Step-by-step explanation:
Since 1cm is to 5m, just multiply 3 by 5 and you will get 15.
∫f(6)-∫f(1) = 1, ∫f(6)-∫f(3)=6, and ∫f(7)-∫f(1)=7. Changing around the first and third equation, we can get ∫f(1)=∫f(6)-1, and ∫f(1)=∫f(7)-7. Then we get that ∫f(6)-1=∫f(7)-7, and that ∫f(6)=∫f(7)-6. Then plug into the second equation, to get ∫f(7)-6-∫f(3)=6 or ∫f(7)-∫f(3)=12. So <span>∫73f(x)dx = 12.</span>
