Answer:
<u>Josie will earn $13.75 and her brother Sean will earn $16.25</u>
Step-by-step explanation:
Given that For every $5.50 that Josie earns, her brother earns $6.50.
Tuesday, they earned $30.00
Using the ratio and the proportional
Josie : Sean : Total
5.5 : 6.5 : 12
x : y : 30
So, x = 5.5 * 30/12 = 13.75
And y = 6.5 *30/12 = 16.25
<u>So, Josie will earn $13.75 and her brother Sean will earn $16.25</u>
