Answer:
Calista prize = $82.256
Seth prize = $101.656
Lailani prize = $116.012
Explanation:
Given in question
Total prize is $300
Calista contribution is 425 hours
Seth contribution is 524 hours
Lailani contribution is 598 hours
Total contribution = calista + seth + lailani
Total contribution = 425 + 524 + 598 = 1547
Then i find per hour cost

![\textrm{Per hour cost}= (\$300)/(1547)=\$0.194](https://img.qammunity.org/2021/formulas/mathematics/high-school/ae77jxcbfzegm70cuirgjdonl9dpqfim9n.png)
