The parking lot in front of the school has 52 parking spaces. The parking lot in the back of the school has 38 spaces. If 39 cars have parked and 1/2 of the spaces of the back are filled, how many parking spaces are still available in the school?
assistant
How many parking spaces are there in the school? ** There are a total of 52 + 38 = <<52+38=90>>90 parking spaces in the school.
How many cars have parked at the back? ** Since half of the spaces are filled then, 38 x 1/2 = <<38*1/2=19>>19 cars have parked at the back.
How many cars have parked in the school? ** So, a total of 39 + 19 = <<39+19=58>>58 cars have parked in the school.
How many parking spaces are still available in the school? ** Therefore, 90 - 58 = <<90-58=32>>32 parking spaces are still available.
