Question 944309: I need to write an algebraic equation for the following word problem:
You work for a delivery service. With plan A you can earn $5 per hour plus $0.75 per delivery. With plan B, you can earn $7 per hour plus $0.25 per delivery. How many deliveries must you make per hour to earn the same amount with either plan?

Let d= number deliveries
Plan A: $5+$0.75d
Plan B: $7+$0.25d
The Question is when does A=B
$5+$0.75d=$7+$0.25d Subtract $5 from each side
$0.75d=$2+$0.25d Subtract $0.25d from each side
$0.5d=$2 Divide each side by $0.5
d=($2/$0.5)=4 ANSWER You earn the same amount with either plan when you make 4 deliveries per hour.
