A firm starts work with 110 employees for the 1st week. The number of employees rises by 6% per week. How many weeks will it take for 250 persons to be employed?



Answer :

SneakyPythagoras
1 % of 110 = 1.1
x 6 = 6.6
round up because you can't have 0.6 of a person.
7 people a week.
250 - 110 = 140
140 divided by 7 = 20
20 weeks
110 x 1.06 = 116.6
Now if 116.6 is x repeat this step till you get 250 people
X x 1.06
, so it will take roughly 14-15 times to get 250 employees but 14 times is the closer one
