Question: What is the Question?
Answer:
(a) $4250,
(b) $5225.
Step-by-step explanation:
Let n represent number of months.
We have been given that John saves $3500 the first month and every month later decreases it by $75.
First of all, we will find formula of John's savings in n months using arithmetic progression, where, 1st term is 3500 and common difference is 75.
, where,
n = Number of terms in a sequence,
d = Common difference.
(a) To find John's savings in 11 months, we will substitute in above formula.
Therefore, John would have saved $4250 in the 11th month.
(b) To find John's savings after 2 years, we will substitute in above formula.
Therefore, John would have saved $5225 in 2 years.
