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
Answer:
C
Step-by-step explanation:
Growth can be represented by the equation 
. We know that r=2% or 0.02 in this situation so we have 1.02. We know t=100 hours and the starting population A=200. We substitute these values and use a calculator to evaluate.
We now use our calculator to evaluate the exponent first and then multiply by 200.
<em> 4 1</em>
<em>u + -- = 2 ---</em>
<em> 5 3</em>
<em> 1 2 * 3 + 1 7</em>
<em>2 ---- = ---------------- = ------</em>
<em> 3 3 3</em>
<em>Now we have to do</em>
<em> 4 7</em>
<em>u + -- = ---</em>
<em> 5 3</em>
<em> 7 4 7 * 5 - 4 * 3</em>
<em>u = ------- - ----- = ------------------------ </em>
<em> 3 5 3 * 5</em>
<em> 35 - 12 23</em>
<em>u = ------------------ = ------</em>
<em> 15 15</em>
