Respuesta :
If Melanie get's 4.10$, then Jacob get's 20.50$.
We can divide to get the unit rate:
20.50 ÷ 4.10 = 5
This means that if Jacob gets 5$, then Melanie will get 1$.
So in this case, Melanie get's 1$.
To solve the problem we should know about the Ratio.
Ratio
A ratio shows us the number of times a number contains another number.
The allowance Melanie gets when Jacob gets an allowance of $5 is $1.
Given to us
- the ratio of Melanie's allowance to Jacob's allowance is 4.1 to 20.5
- Jacob gets $5.00,
Using the ratio
[tex]\dfrac{\text{Melanie's allowance}}{\text{Jacob's allowance}} = \dfrac{4.1}{20.5}[/tex]
[tex]\dfrac{\text{Melanie's allowance}}{\text{\$5}} = \dfrac{4.1}{20.5}[/tex]
[tex]\text{Melanie's allowance} = \dfrac{4.1\times 5}{20.5}[/tex]
Melanie's allowance = 1
Hence, Melanie's allowance is $1.
