Part A At the toaster company, the weekly cost to run the factory is $1400 and the cost of producing each toaster is an additional $4 per toaster. Choose a function rule representing the weekly cost in dollars, f(x), of producing x toasters. A f(x)=1400x+4 B f(x)=4x+1400 C f(x)=4x−1400 D f(x)=1400−4x
The cost of running the factory is £1400 meaning that you need to add the cost of the toasters on. Since the number of toasters produced is unknown we use x to represent that cost
