Read the following passage and determine the constant rate of change. Put it in y = kx form
A runner runs 9 laps in three
minutes and then runs 15 laps in
five minutes.
Identify the constant of
proportionality

i think da answer is

d.square root of 3

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.

so first lets findout how much she spent so whats 32.00 - x = 9.20

32.00 - 22.75 =9.25. so she spent a total of $22.75 okay now we know the amount she spent. so now u got it from here.
