Choice a is a good one by the way
C(h)=80h+210
80h+210=490 subtract 210 from both sides
80h=280 divide both sides by 80
h=3.5 hours
102.6 is the answer to this problem
Answer: 6*Q= 6Q or 6*Q= y
Step-by-step explanation:
The product is the answer to a multiplication problem, therefore 6*Q will be the first part.
The second part will be the answer. Normally, this would be represented just by 6Q, but you can use another letter to represent it. We'll use y for an example.
6*Q= 6Q
or
6*Q= y
