A gym charges a one-time fee of $75 to join, plus membership dues of $25 per month. Which equation represents the total cost, C, of belonging to the gym for m months? A. C = 25m – 75 B. C = 25m + 75 C. C = 75m + 25 D. C = 75m – 25

C = 75 + 25m

Step-by-step explanation:

The one time fee is 75 and membership dues are 25 per month.

This corresponds to C = 75 + 25m because the one time fee is 75 and each month you pay 25.

you should at least use a calculater

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
