I would need more information and a picture of the problem to help you.
Answer: a = 6h + 5b
Step-by-step explanation:
Amount earned per hour = $6
For working h hours in a week,
Amount earned = $6 × h = 6h
Amount earned per sign up = $5
Additional amount earned from selling of cards in a week = 5 × b = 5b
Thus, total amount earned in a week will be 6h + 5b
(1,2.5) would be the solution to the system of equations
