Answer 1

Answer:

Martha is incorrect.

Amount paid by Renee = $\ 340$

Amount paid by Susan = $297.5

Amount paid by Martha = $\ 212.5$

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 = $100-40-35=25\%$

But Martha thinks she will pay 13 of the cost. So, she is incorrect.

Amount paid by Renee = $\frac{40}{100}(850)=\ 340$

Amount paid by Susan = $\frac{35}{100}(850)=\ 297.5$

Amount paid by Martha = $\frac{25}{100}(850)=\ 212.5$
