C = 9

Step by step:

7(c - 12) = -21

We divide both sides of the equation by 7

C - 12 = -3

The we move the constant, - 12, to the right hand side and change its sign.

C = -3 + 12

Then we calculate the sum

C = 9

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

Our mom gives us 10.

3+10=13

Our dad gives us 30.

13+30=43

Our aunt and uncle give us 100.

43+100=143

And we have another 7.

143+7=150

Therefore, we have $150 now.
