Parking garage a charges cars a $3 entrance fee in addition to $2 per hour to park. parking garage b charges a $5 fee to enter but only $1.50 per hour to park. for what number of hours would it cost the same to park at both garages?

It would take 4 hours 

For the first hour you'd pay $5 at A and $6.50 at B
For the second hour you'd pay $7 at A and $8 at B 
For the third hour you'd pay $9 at A and 9.50 at B
And for the fourth hour you'd pay $11 at A and $11 at B

Hope that helps you!
