Answer:
A single cheeseburger order cost $1.23
A single fries order cost $1.28
Step-by-step explanation:
Let the cost of cheeseburgers be c and the cost of fries be f
Mathematically;
4c + 3f = 10.75 ••••(i)
Secondly;
5c + 2f = 11.2 ••••(ii)
We have two equations to solve simultaneously;
Multiply i by 2 and ii by 3
8c + 6f = 21.5
15c + 6f = 33.6
Subtract ii from i
-7c = -12.1
c = 1.73
Recall;
5c + 2f = 11.2
5(1.73) + 2f = 11.2
2f = 11.2-8.65
2f = 2.55
f = 2.55/2
f = 1.28
In order to find, Least common denominator for all of that fractions, you need to calculate the LCM of 8, 18, 9 , 14 ['cause they are denominators ]
It would be 494
So, Your Final Answer would be 494
Hope this helps!

Answer:
$4
Step-by-step explanation:
Given that
total cost of 8 identical pens and 2 identical files is $32
And, the The total cost of 3 such files would be the same as the total cost of 4 such pens
We need to find out the cost of each file
So let us assume the following things
Pens be x
File be y
Now
8x + 2y = $32 ....(1)
3y = 4x.........(2)
y = 4x÷ 3
Now put the value of y in equation 1
8x + 1.33x = 32
x = $3.55
x = $4
