For each hour he babysits, Anderson earns 1 dollars more than half of Carey’s hourly rate. Anderson earns 6 dollars per hour. Which equation can be used to solve for Carey’s hourly rate, c ?

Half of Carey’s hourly rate is dc. Anderson earns $1 more than that amount, so his rate is dc + 1. Since Anderson earns $6 per hour, the equation is dc + 1 = 6. This is choice D, “1 half c plus 1 is equal to 6.”
