Answer 1

Martha is incorrect.

Amount paid by Renee =
`\$340`

Amount paid by Susan = $297.5

Amount paid by Martha =
`\$212.5`

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 =
`(40)/(100)(850)=\$340`

Amount paid by Susan =
`(35)/(100)(850)=\$297.5`

Amount paid by Martha =
`(25)/(100)(850)=\$212.5`
