Ellie:
Total spending = $36.50
Number of popcorn bags bought = 7
Number of drinks bought = 2
Morgan:
Total spending = $155.50
Number of popcorn bags bought = 9
Number of drinks bought = 14
Part 1:
If
P = Price of one popcorn bag
D = Price of one drink
Then,
For Ellie: 7P + 2D = 36.50
For Morgan: 9P + 14 D = 155.50
Set of equations:
7P + 2D = 36.5 --------(1)
9P + 14D = 155.5 ---- (2)
Part 2:
Solving equations (1) and (2)
Multiply (1) by 7 and subtract (2) from resulting equation;
49P + 14D = 255.5
9P + 14D = 155.5
-------------------------
40P = 100
P = 100/40 = 2.5
From eqn (1),
7*2.5 + 2D = 36.5
17.5 +2D = 36.5
2D = 19
D = 19/2 = 9.5
Therefore,
Bag of popcorn costs $2.50
if Bryn is 17 then 3g - 7 =17 so if we add 7 to 17 the equation is
3g = 24 and divide the equation by 3 g = 8
Gabriela is 8
