Renee, Susan, and Martha will share the cost to rent a vacation house for a week. Renee will pay 40 percent of the cost. What fr
Rom4ik [11]

Answer:

Amount paid by Martha = $200

Amount paid by Renee = $320

Amount paid by Susan = $280

Step-by-step explanation:

Here, the given question is INCOMPLETE.

Renee, Susan and Martha will share the cost to rent a vacation house for a week. Renee will pay 40% of the cost. Susan will pay 0.35 of the cost. Martha will pay the remainder of the cost. If the cost to rent the vacation house is $800, how much will each person pay?

Here, the total cost of the vacation  = $800.

Renee pays 40% of the cost.

Calculating 40% of $800, we get:

\frac{40}{100} \times 800 = 320

So, Renee pays a total of $320 in the cost of vacation.  ... (1)

Susan pays 0.35 = 35 %  of the cost.

Calculating 35% of $800, we get:

\frac{35}{100} \times 800 = 280

So, Susan pays a total of $280 in the cost of vacation.  ... (2)

Now, The amount paid by { Renee + Susan  + Martha} = $800

⇒ $320 + $280 + Amount paid by Martha  = $800

⇒Amount paid by Martha = $800 - $600 = $200

Hence, Amount paid by Martha = $200

Amount paid by Renee = $320

Amount paid by Susan = $280

Solve the inequality r-(-5)>-2
Jet001 [13]

Answer:

r>-7

Step-by-step explanation:

Solving an inequality is similar to solving an equation. To solve for r, isolate it. Whatever you do to one side, do to the other. Remember that a negative and a negative equal a positive, thus one side of the inequality becomes r + 5. Then, subtract both sides by -5 to find the answer.

r-(-5) >-2\\r+5>-2\\r>-7

Phoebe wants to get atleast a grade of 90 in the math class. Her grade will be the average of two tests. She scored a 94 on the
marin [14]
First things first, you will have 94 + x. Place those on top of a fraction bar and on the bottom put the two numbers over 2. So you have 94 + x over 2. Then, write the symbol ‘greater than or equal to’ and on the other side place your 90. So, 90 + x over 2 is greater than or equal to 90. This is a difficult thing to write out and explain so I hope this makes sense. :)
