I believe your answer is -220w-22
2-3(2w+1)=7w-3(7+w)
+7w -7w
2-3(9w+1)=-3(7+w)
+w -w
2-3(10w+1)=-3(7)
2-3(10w+1)=-21
-1(10w+1=-21
-21 +21
-22(10w+1)
-220w-22
You're going to want to take the total, which is $353.00 and subtract the initial cost, which is $84.00, the number now should be $269. Using that total divide it by $68.00, there you should find your answer of about 4 hours. The precise answer is 3.99588235. But you would round that to 4 hours.
