Answer:
Explanation:
$3.50+$1.50=$5.00
So proportion of the price money will be
divided in 3.5/5 and 1.5/5
To make a percentage, first lets multiply our fractions by 10/10
so our new fractions are 35/50 and 15/50.
Now multiply our new fractions by 2
70/100 and 30/100.
So if they win Costa is going to get 70% of the winnings and Sheila is going to get 30% of the winnings.

so Costa will get $700
and Sheila will get the rest $1000-$700 = $300
