Is it asking for the line C's measurements? If so, is it line AC or BC?
Answer:
$135
Step-by-step explanation:
We need to find the profit first.
1.75 x 500 = 875.
$875 is how much money they have. We need to find the total cost it took to make the pencils and then subtract that from the money they have, to find the profit.
0.40 x 500 = 200
so subtract.
875 x 200 = 675.
So they mad $675. To find twenty percent of that, we need 20% as a decimal and multiply it by 675.
0.20 x 675 = 135
$135

The first thing you should do for this case is to use the following table to perform the equation of a line:
y x
41,431 1995
48,729 2005
We have then that the line that best fits this data is
y = 729.8x - 1E + 06
Then, to know in what year the number of shopping centers reaches 80,000 we must replace this number in the equation of the line and clear x:
80000 = 729.8x - 1E + 06
Clearing x
x = (80000 + 1E + 06) / (729.8) = 1479.857495
nearest whole number
1480
This means that after 1480 years, 80000 shopping centers are reached.
Equivalently, this amount is reached in the year:
1480 + 1995 = 3475
In the year 3475
answer
(a) y = 729.8x - 1E + 06
(b) In the year 3475
Answer:
rs. 81
Step-by-step explanation:
given,
mp. = 1620
sp. = 1539
now,
discount = mp - s.p = 1620 - 1539 = 81
