GIVEN
1) Females outnumber males by 3 to 2.
2) There are 1770 people in the city.
SOLUTION
Let the number of males be x and the number of females y. Therefore, the total number of people can be written to be:
If there are 3 females for every 2 males, we have that:
We can substitute equation (2) into equation (1) and solve for y:
Dividing both sides by 5, we have
There are 1062 females in the county.

Simple interest formula
Compound interest formula
a.
Simple interest is $125
b
.
Compound interest is $125

e
.
the compound interest is $385
f. the result compared, compound interest is $10 more than simple interest
g.
the simple interest is $600
h.
the compound interest is $4869
i. the result from g and h, h is over 8 times bigger than g.
j. interest compound annually is not the same as simple interest, only for the case of a and b seeing that it is for 1 year. but for 2years and above there is difference as seen in c to h
