3x + 17 = 7x - 15
- 3x - 3x
17 = 4x - 15
+ 15 + 15
32 = 4x

Answer:
C=550 pounds
Step-by-step explanation:
Given the formula: C=p(t+30)
and with p=2 and t=245 known.
We can plug our values of p and t into our formula. Once we do this, the only unsolved variable will be C.
C=2(245+30)
Add 245+30 first because they are in parentheses and we must abide by the order of operations.
C=2(275)
Now we just multiply 2(275) because this is all that's left in the formula.
C= 2*275 = 550
We now know that C=550 when p=2 and t=245, but we need to apply units to finalize the answer. We are told that C represents the total cost in "POUNDS", so pounds is our units for variable C.
Our final answer is...
<u>C=550 pounds</u>
