The cost of the 4 posters combined is $7.40 and we need to find out how much each poster costs if they are all priced the same.
Since the total cost is evenly distributed among all the posters, an effective way of finding a price per poster is to divide the total cost by the number of posters.
Hence we divide $7.40 by 4. Increasingly, $7.40 divided by 4 is $1.85.
So each poster costs
Answer: $1.85.
