Answer:
let the number of bags of popcorn = x
let the number of drinks = y
4x + 2y = 20.50 --- (1)
6x + 4y = 34.50 --- (2)
from (1) 4x + 2y = 20.50
2y = 20.50 - 4x
y = 10.25 - 2x --- (3)
substitute (3) into (2)
6x + 4y = 34.50
6x + 4(10.25-2x) = 34.50
6x + 41 - 8x = 34.50
-2x = 34.50 - 41
x = -6.5 / -2
x = 3.25 --- (4)
substitute (4) into (3)
y = 10.25 - 2x
y = 10.25 - 2(3.25)
y = 3.75
the price of one bag of popcorn = $3.25
the price of one drink = $3.75
Answer:
60
Step-by-step explanation:
if its 20 rotation it goes 3 times it will be 60
20 20 20= <u>60</u>
In order to solve this problem, you need to find out how 3 of something is 30
In this case, you multiply 10.
Sean= 3×10=30
Ryan= 4×10=40
Justin= 5×10= 50
30+40+50= 120
The answer is $120
Hope this helps
We can plug in the x values to find the solution.
If we plug in 40.25 the final solution is 143, which also matches 160-17 (143)
The answer is 40.25
