Question

Quizplus · Accepted Answer

Let x be the number of toys produced and y be the cost to produce x toys.

The fixed cost is $90, which means that when x=0, y=90.

The cost to produce plastic toys increases by 10 cents per toy, which means that the rate of change in y with respect to x is 0.10.

Therefore, the linear model is:

y = 0.10x + 90

Choice B matches this linear model.
