Answer:
Either 12/5 or 2 2/5
Step-by-step explanation:
I times 16 and 9 together to make 144
and 3 and 20 together to make 60
144/60= 12/5 or 2 2/5
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
