1 The graph shows the cost of producing gadgets. If the
cost to produce gadgets triples due to increased
production costs, which equation best represents the
new cost C of producing n gadgets?
Cost (5)
0
100 300 500 700 900
Number of Gadgets
A C = 300n
B C = 30n
C C = 3n

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

answer:

c. the third graph

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
