Answer:
Popcorn cost $1 each
Drinks cost $5.25 each.
Step-by-step explanation:
Let the price of each popcorn be X
And the price of the same drink be y
Statement one translates to;
8x + 5y = 34.25-----------------------------(1)
Statement for Elijah translate to;
2x + 8y = 44-----------------(2)
x = 22- 4y [ dividing through by 2 and making X the subject formula]----------(3)
Substitute (3) in (1); we have :
8 ( 22-4y) + 5y = 34.25
176 -32y + 5y = 34.25
176-34.25 = 32y-5y
141.75= 27y
y= 141.75/ 27 =5.25
From, (3)
x= 22- 4(5.25)= 22-21 =1
I hope this helps! let me know
