<h3>What is a Ratio?</h3>
A ratio shows us the number of times a number contains another number.
The ratio of the ages of Mandy and Sandy is 2:5. Therefore, the ratio will be,
M/S = 2/5
M = 2S/5
After 8 years, their ages will be in the ratio 1:2, therefore,
(M+8)/(S+8) = 1/2
2M + 16 = S + 8
2M - S = -16 + 8
Substitute the value of M,
2(2S/5) - S = -8
-0.2S = -8
S = 40
Now, if we substitute the value of S in the first ratio,
M/S = 2/5
M/40 = 2/5
M = 16
Now, if we take the difference in their ages the difference will be 24(40-16).
Since the difference is 24, we can conclude that Caitlin is right.
Hence, Caitlin is right.

Step-by-step explanation:
The Program rating of a program is the percentage of TV households in an area that are tuned to a specific program during a specific time period.
The designated market area (DMA) of Boston has approximately 3 million television households.
Audience research shows that 45 percent of these households had their sets turned on during a particular Saturday evening.
45% of 3 Million = 0.45 X 3000000 = 1,350,000
Out of these 1,350,000, 300,000 households were watching Sports Stories.
Therefore, the program rating for Sports Stories in the Boston DMA is:
