Final answer:
To find Melanie's allowance, set up the proportion 4.1 to 20.5 as Melanie's allowance to Jacob's $5.00. The calculation shows that Melanie receives $1.00. The correct answer is B) 1.00.
Step-by-step explanation:
To find the amount of allowance Melanie receives in comparison to Jacob's allowance, we establish a proportion based on the given ratio. The ratio of Melanie's allowance to Jacob's allowance is given as 4.1 to 20.5. If Jacob receives $5.00, we can set up a proportion to solve for Melanie's allowance.
Let's denote Melanie's allowance as M. According to the ratio, we can write the proportion as:
4.1 / 20.5 = M / 5.00
By cross-multiplying, we get:
20.5 * M = 4.1 * 5.00
Now we solve for M:
M = (4.1 * 5.00) / 20.5
M = 20.5 / 20.5
M = 1.00
Therefore, Melanie receives $1.00. The correct answer is B) 1.00.
