You invest $500 into an account that collects 1% interest each month. If you add an additional $50 each week, what will the balance of the account be after 5 months?

Answer:
$1555.91
Step-by-step explanation:
First Month:
You start out with $500.
You add $200 in the first month, and have 700.
Multiply 700 by 1.01, to add the interest and you get 707.
Second Month:
707 + 200 = 907
907 x 1.01 = 916.07
Third Month:
916.07 + 200 = 1116.07
1116.07 x 1.01 = 1127.2307
Fourth Month:
1127.2307 + 200 = 1327.2307
1327.2307 x 1.01 = 1340.503007 (round to .50)
Fifth Month:
1340.50 + 200 = 1540.50
1540.50 x 1.01 = 1555.905
Round to 1555.905 1555.91, and there's your answer. Hope this helps!
