Question

Anatoly graphed his store’s costs below. Which statement best describes the rate of change in anatomy’s graph?

Answer 1

Ansswer: C. Anatoly's costs decrease by $50 for every unit sold

Explanation:

In this graph Cost (in $100) has been plotted on Y axis and Units sold on X axis. It is evident from the graph that at zero sale per unit cost was $1600 which reduced down to $1400 when 4 units were sold.

Therefore from $1600 to $1400 cost was reduced by $200 and 4 units were sold.

So reduction in cost per unit will be = $200/4 = $ 50

which is the final answer.
