Target charges $90 to design a room and $10 per hour they are at your house. Walmart charges $80 to design a room and $25 per hour they are at your house. Which equation could be used to find the number of hours for which the cost of both stores is the same?
115h = 90h
h(90 + 10) = h(80 + 25)
90h + 10 = 80h + 25
90 + 10h = 80 + 25h
Bob has $50 and spends $2.50 every day. Henry has $5 and saves $2.50 every day. Which equation could be used to determine when they have the same amount of money?
50 - 2.50x = 5 - 2.50x
50 - 2.50x = 5 + 2.50x
50x - 2.50 = 5x + 2.50
(50 - 2.50)x = (5 + 2.50)x
