The baseball team has sold tickets to a spaghetti dinner. forty-eight student tickets have been sold at $1.50 each. if the baseball team has made $149 total from the sale of all tickets, and adult tickets cost $3.50, how many adult tickets were sold?

Let the number of adults be x

number of students is 48

Amount collected from students=48 * (1.5) = $72

Amount collected from adults=3.5*x=3.5x

Total amount collected will be:

72+3.5x=149

solving for x we have:

3.5x=149-72

3.5x=77

thus

x=77/3.5

x=22

thus the number of adults was x = 22
