Write a rule for the amount of money contributed to the plan after "n" months.

Suppose your salary inreases by $1400 each year. Write a rule to describe your salary during the "n"th year.

**really need help...**, Monday, December 10, 2007 at 6:29pmwell for the first one...i came up with

is that right?

**Damon**, Monday, December 10, 2007 at 6:35pmAh, your monthly salary is 28,200/12 and it is the monthly, not yearly figure you need for the first part.

**Damon**, Monday, December 10, 2007 at 6:41pmNow we all wish it worked by a power law like that but unfortunately it is just the same amount every month

that amount the first month

that again for a total of 2 thats

that a third time for a total of 3 thats

**Damon**, Monday, December 10, 2007 at 6:45pmNow do the second part the same way, except now it does indeed go by years.

Again it increases by a constant amount every time period, not by a percentage of the previous amount. That makes it much simpler than it would be otherwise.

**really need help...**, Monday, December 10, 2007 at 6:53pmokay so if it says ...how much will u have ontributed to the plan after 6 months...should i do:

28,200/12 x (.1)to the n-1 power

or should i not divide by 12?

- MATH!!! -
**Damon**, Monday, December 10, 2007 at 7:25pmIt is not to the power at all

it is just the number of month times the contribution every month which is 2350 times n

**Damon**, Monday, December 10, 2007 at 7:35pmNow the second one is the same theory, again nothing to a power.

first column year

second column salary

1 28,200 salary increases by $1400 each year.

2 28200+ 1400=29600

3 28200+ 2*1400 =31000

4 28200+ 3*1400 =32400

....

n 28200+(n-1)*(1400)
