Answer:
D $900
Step-by-step explanation:
You just round all of the numbers to their nearest hundred.
EXAMPLE: $395 is closer to $400, than it is to the hundred before it, $300. Therefore you would "round" it up to 400.

Answer:

Step-by-step explanation:
I have the same question and i figured it out so here you go!!!
Answer:
Peter swam 12 hours, Pam swam 6
Step-by-step explanation:
Pam = x
Peter = y
y = 2x (this is because Peter swam twice as much)
y + x = 18 (this is because they both swam a total of 18 hours)
2x + x = 18 (substitute for y)
3x = 18
x = 6 (pam)
Now, I just need to substitute x = 6 into original equation.
y = 2(6)
y = 12 (peter)
