You’re assisting a craft vendor at a fair who sells 5 knit hats for $9.50 each. she then sells the sixth and seventh for $11.25 each, and the eighth and ninth for $8.75 each. at the end of the fair, she is charged 15% of her gross earnings for the booth space. how much money does she make after paying for the booth space?

$13.125 = 15%

87.5 - 13.125 = $74.375

Step-by-step explanation:

5 x 9.50 + 2 x 11.25 + 2 x 8.75 = 87.5

87.5 x 15 divided by 100 = $13.125

step-by-step explanation:

the given growth  function for the length of the fish (cm) is

f(m) = 5(1.07)m = 5.35m

where 

m = months

at the end of the study, the length is 9.19 cm. the  time for conducting the study is determined as

5.35m = 9.19

m = 1.7178 months

part a.

the study was performed over a time period  of about 1.72 months. therefore  the domain for  plotting the function is 0 < = m < = 1.72.

note:

if growth  continues at this rate for up to m months, then the domain would be 0< =m< =m.

part b.

the growth function is a linear function.

when m=0, f=0.

therefore the initial growth is zero, which represents the y-intercept.

part c.

assume that the growth function is valid for 0< =m< =9.

the average rate of change of the function is the slope of the linear function, which is 5.35 cm/month.
