Answer:
110 + 25x = Total Cost (or any type of variable needed, like a,b,c, etc.)
Step-by-step explanation:
Since the monthly fee occurs more than once, and we don't have the number of months, we put an x to represent the amount of months. The $110 is the one time additional fee for the membership, so it doesn't need a variable.
Answer: 75 people
Step-by-step explanation:
1).
we have percentage of people who invested in 18-29 year category
=31%
we need
n=40 people
this is
30% of x =40
or
0.3x=40
x=40/0.3 =133.33 or 134 people
2).
in 65+ category
percentage =54%
we need
n=40
this is
54% of x =40
or
0.54x=40
or
x=40/0.54 =70.07 or 75 people
