Chris has a credit card with a balance of $5,400 and an APR of 22.5%. With the monthly payments he has been making, Chris would be able to pay off his credit card in 18 months. After receiving a promotional offer in the mail, Chris decides to transfer his balance to a new credit card with a 15% "introductory" APR for the first 12 months. After 12 months, the APR increases to 23%. How much will Chris save in finance charges (interest) if he pays off the credit card before the introductory APR expires? Please explain how you got it thank you.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
