Package a contains 3 birthday cards and 2 -you notes and costs $9.60. package b contains 8 birthday cards and 6 -you notes and costs $26.60. if x represents the cost of a birthday card and y represents the cost of a -you note, how much does each birthday card cost?

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.

the cost of 6 show tickets is $30.

step-by-step explanation:

look closely at the graph, where it says 6 that's the amount of tickets. go up until you reach the dot. the dot shows that the coordinates are (6, 30). there fore from that you can infer that 6 show tickets cost $30.
