Algebra i: a function approach part 2
hilary earns $7 per hour at her weekend job. the second week she worked two hours
less than she worked the first week. her total pay for both weeks was $168. which
equation can be used to find f, the number of hours she worked the first week?
7f + 7(2-1)= 168
7f+ 7(f + 2) = 168
78-2168
78 + 7(f - 2) = 168
