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

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

Step-by-step 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.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

step-by-step explanation:

gym b charges $1.05 less per hour than gym a.
