Answer:
66
Step-by-step explanation:
10% of 330 = 33
another 10% of 330 = 33
therefore, 20% of 330 = 66
If $0.35=1 ounce
?=8.5 ounces
8.5/1*$0.35=$2.975 Therefore 8.5 ounces cost $2.975
If 1 ounce =$0.35
12.2 ounces=?
12.2/1*$0.35=$4.27
Therefore 12.2 ounces cost $4.27

Answer:
Maximum speed of bird A is 
Maximum speed of bird B is 
Step-by-step explanation:
This is a problem with two unknowns: Max speed of bird A (we name that "A"), and max speed of bird B (we call that "B"). Now we can create two equations with these two unknowns, based on the info provided:
Equation 1): based on the phrase "bird A can travel six times as fast as bird B" we write:

Equation 2): based on the phrase; "the total speeds for these two birds is 224 miles per hour", we write:

Now, we use the first equation to substitute A in the second equation, ad then solve for the unknown B:

Now we can solve for the other unknown "A" using the substitution equation and the value of B we just found:
