6. Zarah keeps RM80 in her 'Giant Fund' at the end of the first month and continues saving every month, RM10 more than the previous month.
Ali however, keeps RM100 in the first month in his 'Lion Fund and
continues saving 5% more than the previous month.
(a) Just after Zarah's RM280 deposit, determine the number of weeks
that she has saved the money.
(b) How much is in Ali's 'Lion Fund' after 20 months?

Can someone help me?
