Increased by 125%

Step-by-step explanation:

1) subtract the values 4.50 and 2.00 to get 4.50 - 2.00 = 2.50, cost goes up by $2.50

2) divide 2.50 by the original price of 2.00, and you get 2.50/2.00 = 1.25

3) move the decimal point 2 spots to the right to go from 1.25 to 125%

4) the cost has increases by 125%

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.

answer is  

c.

56

hope you get this right
