Question

Renee, susan, and Martha share the cost to rent a vacation house for a week

renee will pay 40 percent
susan will pay 0.35 of the cost
Martha will pay the rest
she thinks she will pay 1/3 of the cost is she correct ?

Answer 1

No, because 40%+35%=75%.
1/3%= 66.667
Therefore Martha is not paying 1/3 the cost.
p.s. Martha has the best deal, that cheapo!
