Answer:
Martha is incorrect.
Amount paid by Renee = [tex]\$340[/tex]
Amount paid by Susan = $297.5
Amount paid by Martha = [tex]\$212.5[/tex]
Step-by-step explanation:
Given: Renee will pay 40% of the cost. Susan will pay 0.35 of the cost.Martha will pay the remainder of the cost. Martha thinks she will pay 13 of the cost.
To find: Is Martha correct?
To find: amount paid by each of Renee, Susan, and Martha
Solution:
Percentage of an amount paid by Renee = 40%
Percentage of an amount paid by Susan = 35%
So,
Percentage of an amount paid by Martha = [tex]100-40-35=25\%[/tex]
But Martha thinks she will pay 13 of the cost. So, she is incorrect.
Amount paid by Renee = [tex]\frac{40}{100}(850)=\$340[/tex]
Amount paid by Susan = [tex]\frac{35}{100}(850)=\$297.5[/tex]
Amount paid by Martha = [tex]\frac{25}{100}(850)=\$212.5[/tex]
