An animal shelter spends $1.50 per day to care for each cat and $3.50 per day to care for each dog. Gianna noticed that the shel
ter spent $20.50 caring for cats and dogs on Tuesday. Gianna found a record showing that there were a total of 7 cats and dogs on Tuesday. How many cats were at the shelter on Tuesday?
First we have to see in both cases what is the cost of one ticket in the fist case 12.5/5=2.5 in the second case 20.16/8=2.52 therefore 5 tickets for 12.5 is the better deal
