Respuesta :

Answer:

Martha is wrong.

Step-by-step explanation:

Let the cost of the house is C.

Payment by Ranee = 40% of the cost

=40% of C

=[tex]\frac{40}{100}\times C[/tex]

=0.40 C

Payment by Susan = 0.35 of the cost

=0.35 C

Combined payment by Ranee and Susan = 0.40C + 0.35C=0.75C

The remaining payment will be done by Martha.

So, the remaining payment = C- 0.75C=0.25 C

Hence, Martha will have to pay 0.25 of the cost or 25% of the cost.

So, Martha is wrong.
