Hello!

If Betty had $10 left in her pocket, she spent $30. We can divide this by 12 to find the unit price for each bag of popcorn.
30/12=2.5

Our answer is B)2.50

I hope this helped!

(15,12) would work but the total is 600. (13,11.5) would work and the total is 547.5. (10,13) would work because the total is 525. the rest of the options won't work because the order of large jackets is not twice less than the number of small jackets. Hope that helps.
