What should I answer?

Step-by-step explanation:

Answer 2

Jim's payment is more than Jabu's after four months and Jabu's payment is more than Jim’s after five months.

It is given that Jim’s gym takes a deposit of 150 and a monthly charge of 120.

Let x be the number of months for which both are paying the charges.

Then, Jim's total charge=150+120x.

Now, Jabu’s gym takes no deposit and takes a monthly charge of 150.

Jabu’s gym total charge=150x

Substitute x=4 in the obtained expression to determine the total payment of both after four months.

Jim's total charge=150+120(4)

=150+480

=620

​Jabu’s gym total charge=150(4)

=600

So, Jim's payment is more than Jabu after four months.

Substitute x=5 in the obtained expression to determine the total payment of both after five months.  

Jim's total charge=150+120(5)

=150+600

=750

Jabu’s gym total charge=150(5)

=750

​So, Jabu's payment is more than Jim’s after five months.

Therefore, Jim's payment is more than Jabu's after four months and Jabu's payment is equal to Jim’s after five months.
