Answer: $3510
Step-by-step explanation:
Fro th question, Alice, Bryan and Cindy share the cost of renting an apartment in the ratio 3:6:4 respectively and we.are informed that Alice pays $810 monthly.
Alice ratio = 3
Bryan's ratio = 6
Cindy's ratio = 4
Total ratio = 3+6+4 = 13
Since Alice has a ratio of 3, this means that Alice pays 3/13 of the total monthly rent. Let the total rent be x. Therefore,
3/13 of x = 810
3/13 × x = 810
3x/13 = 810
3x = 810 × 13
3x = 10530
x = 10530/3
x = 3510
Therefore, the monthly rent is $3510

How to solve world problem ?</h3>
Endeavor to understand the question, analyze it and interpret it into equation.
Given that Helen's age is multiples of 4. Next year it'll be a multiple of 3. Helen's older brother is now 19.
This means Helen current age is multiple of 4 and next year it will be a multiple of 3. Also, Helen's age is less than 19
The two available numbers that fit this analysis and less than 19 are 8 and 9. 8 is multiple of 4. 8 + 1 = 9 which is multiple of 3
Therefore, Helen is 8 years old now
