For a show, a band will be paid $150 plus $5 for each ticket sold.  Write an equation for their total payment (p) related to the number of tickets they sell (t).

• p = 150 + 5t

• p = 5 + 150t

• p + 5t = 150

• 5t - 150 = p

Lindsay had $40. She works at the grocery store and earns $15 each day.
Which equation shows the relationship between Lindsay's savings (y) and the number of days Lindsay works (x)?

• y = 15x + 40

• x = 15y + 40

• y = 40x + 15

• y = 40 - 15x
