Answer 1

Martha is incorrect. She will pay 1/4 of the cost.

Explanation:

(40% + 0 35 . )

1- ( . 0 40 + 0 35 . )

Answer 2

No, Martha is incorrect.
To find out how much Martha must pay, she must add up .4 + .35. It equals = .75. So Martha must pay the rest of it, so 1 - .75 = .25.
So Martha pays 1/4 of the cost.
