Product is multiplying. when you multiply a letter with a number you don't put any symbols so it would be 8c
B I think not sure ......
1.5 is lesser than 0.5. Oh, wait nevermind I meant to say -1.5 is lesser than 0.5
First, multiply both sides by 1000
1000*c = w*t*c
Since c is on both sides, they would cancel each other out
1000 = w*t
Divide both sides by t.
w = 1000*t
