First you should get whole number of money
167+30=197$$
Thn you should divide it on the 4 families
197^4=49.25$$
So every family spended 49.25$$$
Using a geometric series, it is found that he swims 1897 yards in the first week.
In a geometric series, the quotient between consecutive terms is always the same, and it is called common ratio q.
The general equation of a geometric series is given by:
In which is the first term.
The sum of the first n terms is given by:
In this problem:
- 200 yards on the first day, thus .
- Each day, the distance increases by 10%, since 100% + 10% = 110% = 1.1, .
- First week is first 7 days, thus
Then:
He swims 1897 yards in the first week.

Step-by-step explanation:
Its math Its math
You have the correct answer
Solving 8x+7x+5x = 180 leads to x = 9,
which means the smallest angle is 5*x = 5*9 = 45
