Robin can clean 727272 rooms in 666 days. how many rooms do she clean in 9 days
Answers
Answer:
Robin can clean 9828 rooms in 9 days
Step-by-step explanation:
Since Robin can clean 727272 rooms in 666 days, we can find how many rooms she can clean in 1 day by dividing 727272 by 666
number of rooms cleaned by Robin in 1 day = 727272 rooms/666 days = 1092 rooms/day
We can then find how many rooms she can clean in 9 days by multiplying 1092 by 9
1092 rooms/day * 9 days = 9829 rooms

We can get this by solving for the line using the points given. First we need to find the slope.
m(slope) = y1 - y2/x1 - x2
m = 6 - - 2/-2 - -4
m = 8/2
m = 4
Then we can find the y-intercept using slope intercept form with either given point and our newly found slope.
y=mx + b
6 = 4(-2) + b
6 = -8 + b
14 = b

Answer:
The percentage increase in the production cost of the printer is 3%.
Step-by-step explanation:
We are given that the production of a printer consists of the cost of raw material at 100 dollars the cost of overheads at 80$ and wages at 120$.
Also, the cost of raw materials and overheads are increased by 11% and 20% respectively while wages are decreased by 15%.
Cost of raw material = $100
Cost of overheads = $80
Cost of wages = $120
So, the total cost of the printer = $100 + $80 + $120
= $300
Now, the increase in the cost of raw material = $100 + 11% of $100
=
= $100 + $11 = $111
The increase in the cost of overheads = $80 + 20% of $80
=
= $80 + $16 = $96
The decrease in the cost of wages = $120 - 15% of $120
=
= $120 - $18 = $102
So, the new cost of a printer = $111 + $96 + $102 = $309
Now, the percentage increase in the production cost of the printer is given by;
% increase =
=
= 3%
Hence, the percentage increase in the production cost of the printer is 3%.
