Answer:
Yes, it's enough information
Step-by-step explanation:
yes, there is enough information to determine the cost of 1 pack of pencils and 1 pack of pens
we just need an algebra of elimination and substition to find the coat of each. like this:
pencils = C
pen = N
2 C + 3 N = 8.25 (times by 2)
5 C + 2 N = 11.00 (times by 3)
------------------------- - (we eliminate the N)
4 C + 6 N = 16.50
15 C + 6 N = 33.00
------------------------- -
-11 C = - 16.5
C = (-16.5) : (-11) = $ 1.50
so the price of 1 pack of pencils is $ 1.50
now we use subtitution to find the price of 1 pack of pens
2 C + 3 N = 8.25
2 (1.50) + 3 N = 8.25
3.00 + 3 N = 8.25
3 N = 8.25 - 3.00
3 N = 5.25
N = 5.25 : 3 = $ 1.75
so the price of 1 pack of pencils is $ 1.75
Answer:
$105.60
Step-by-step explanation:
I think...
For number one, you will divide 15.7 by 5. This is becuase all the strawberries are the same size and mass. This will give you 3.14 or choice C.
For number 2, you will divide 35.37 by three because there are 3 shirts for the same price. This will give you 11.79 or choice C.
For number 3, you will divide 1.28 by 16 since there are 16 of the same size cookies. This will give you 0.08 or choice B.
It crosses the y-axis at 2 bc y=mc+b b is your y intercept
$120 per each student x 495 students = $59,400
Hope this helps!
