Gabriel is signing up for a gym membership with a one-time fee to join and then a monthly fee to remain a member. The the monthly fee is $40 and the one-time joining fee is $100. Write an equation for C, C, in terms of t, t, representing the total cost of the gym membership over tt months. C=?

Answer;

T=100+40c

Step-by-step explanation:

T is the total cost so everything has to add up to that. 100 is a flat cost, plus 40 dollars a month for however long you stay with that program.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
