Kelly works at her own nail salon. Today, she did 9 manicures and received $47.25 overall in tips. If x represents the cost of each manicure, which of the following equations can be used to find the total amount of money she earned,
including tips, for her nail salon today?
A y = 9x + 47.25
B. y = 47.25(x +9)
c. y = 47.25x + 9
D
y = 9(x + 47.25)

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
