Question

Salma, Renata, and Rachel will share the cost to rent a vacation house for a week.

Salma will pay 40% of the cost.
Renata will pay 0.35 of the cost.
Rachel will pay the remainder of the cost.

A) Rachel thinks that she will pay 1/3 of the cost. Is Rachel correct?

B) The cost to rent a vacation house for a week is $850. How much will Salma, Renata, and Rachel each pay to rent this house for a week?

Answer 1

Okay so 40% of 850 is 340
to make 0.35 a percent u just move the decimals 2 to the right and get 35%
35% of 850 is 297.50
so 340+297.50= 637.50
so 1/3 as a percent is 0.33 again to make that a percent we move the decimals shich gets 33%
33% of 850 is 280.50
637.50+ 280.50 =918 which is more than the amount to rent so
A. NO, SHE WILL PAY LESS

Answer 2

what about part B?

Answer 3

First change all the values into decimals.
Salma-0.4
Renata-0.35
Rachel-0.25

Multiply each value by 850.
Salma-0.4*850=
Renata-0.35*850=
Rachel-0.25*850=

The value you get for each one is your answer for B.

Answer 4

part b is easy too you just have to figure out how much is she actually going to pay which is 25% because of one person is paying 40% and one is paying 35% which 75% of the cost so 25% is missing that is what i think

Answer 5
