Answer:
y=105
Step-by-step explanation:
82+75+x=180
157+x=180
x=23
82+23=y
105=y
At x = 0, y = 5.
At x = 1, y = 10.
At x = 2, y = 20.
At x = 3, y = 40.
y is greater than 50 before x reaches 3.5.
If we check each choice:
A cannot be true, or else the y-values should be increasing by 10 each month (ex. 10, 20, 30, 40, 50).
B cannot be true, or the y-values would be decreasing.
C cannot be true, or the y-values should be increasing much faster (ex. 10, 100, 1000, 10000)
D is true, since the y-values are doubling (5, 10, 20, 40).
So the correct answer is D.
So here is how we are going to answer the problem above:
Given that f is the cost of French fries and b is the cost of Hamburger.
So: 5f + 6b = 4.55
5f = 4.55 - 6b (multiply both sides by 6) and we get
30f = 27.3 - 36b
Next,
6f + 10b = 7.00 (multiply both sides by 5) and we get
30f + 50b = 35 (Now substitute the value of 30f)
27.3 - 36b + 50b = 35
14b = 35 - 27.3
14b = 7.7 (divide both sides by 14)
b = 0.55
Therefore, the cost per hamburger is $0.55
Now go back to the cost of fries:
30f = 27.3 - 36b
30f = 27.3 - 36(0.55)
30f = 27.3 - 19.8
30f = 7.5 (divide both sides by 30)
f = 0.25
Therefore, the cost per french fries is $0.25
Hope this helps.
