The total cost when Q = 10 is $150
Step-by-step explanation:
Th equation y = mx + b represents any linear function, where
- m is the unit rate
- b is the fixed amount
∵ The fixed costs are $100
∵ The variable costs are $5 per unit
∵ There are Q units
- Represent the total cost by the function c(Q)
∴ c(Q) = 5 Q + 100, where c(Q) is the total cost of Q units
∵ c(Q) = 5 Q + 100
∵ Q = 10
- Substitute Q by 10
∴ c(10) = 5(10) + 100
∴ c(10) = 50 + 100
∴ c(10) = 150
The total cost when Q = 10 is $150
