The number of trucks calculated using system of equations is 30
Let :
Number of trucks = a
Number of cars = b
Charge per car = $4
Charge per truck = $6
We could form a system of equation thus:
- a + b = 200 - - (1)
- 6a + 4b = 860 - - (2)
From (1)
b = 200 - a
- Substitute b = 200 - a in (2)
6a + 4(200 - a) = 860
6a + 800 - 4a = 860
2a = 860 - 800
2a = 60
a = 30
Therefore, the Number of trucks is 30

Answer: The last choice is correct
The function is a parabola U-shaped up... so it's vertex y-value is the lowest y-value of the function.

Start: $1.63
Change #1: +m
New price 1.63 + m
Chang #2: 1.63 + m - 0.12
New price: 1.63 - 0.12 + m = 1.51 + m
Answer: B) m + 1.51
To find the unit rate you would need to find the cost per ounce of potato chips. To find this you would simply divide. $3.80/20 = .19
So the unit rate in your question is $0.19
Hope this helps! :)
