Answer:
2x + 9y = 60
10x + 5y = 60
The price of each bag of popcorn is $6.
Step-by-step explanation:
Let each drink costs $x and the price of each bag of popcorn is $y.
So, from the given two conditions we can write two different equations as
2x + 9y = 60 ............... (1) and
10x + 5y = 60 ................. (2)
Now, solving those two equations we get,
5(60 - 9y) + 5y = 60
⇒ 300 - 45y + 5y = 60
⇒ 40y = 240
⇒ y = 6
Therefore, the price of each bag of popcorn is $6. (Answer)

Answer:
a. 277.3 m²
b. $307.86
Step-by-step explanation:
a. Area of the wall to be painted = area of rectangle - area of triangle
= L × W + ½×a×b×sin θ
L = 17 m
W = 14 m
a = 8.7 m
b = 9.5 m
θ = 72°
Plug in the values into the equation
Area of the wall = (17×14) + (½*8.7×9.5×sin 72)
Area of the wall = 238 + 39.3024105
Area of the wall to paint ≈ 277.3 m²
b. 20 liters of paint of 1 container cost $21.99
If 1 liter of paint covers 1m², therefore,
277.3 m² will need = 277.3 × 1 = 277.3 liters of paint.
20 liters = 1 container of paint
277.3 liters = 277.3/20 = 13.865 ≈ 14 containers
1 container = $21.99
14 containers = 21.99 × 14 = $307.86
