b= a/3 - 4c/3.

Step-by-step explanation:

good luck let me know if that is it.

It is 6 $ per hour and you need to make 40 hours you would multiply 6 *40 = 240so s = 240 + 9ypart c: substitutesince andrew earned 330 you would substitute it for s 330 = 240 + 9y < solve for y330 ( - 240 ) = 240 ( - 240 ) 9y < subtract 240 from each side 90 = 9y 90 / 9 = 9y / 9 < divide by 9 10 =y andrew worked 10 hours for overtime check 330 = 240 + 9(10)330 = 240 + 90 330 = 330 < -- your answer is 10
