Carmen bought $8 of corn. Carmen bought 24 wars of corn but 6 ears of corn cost $2. 24 divided by 6 is 4. Which means Carmen bought 4 sets of 6 ears of corn. As Carmen bought four sets of 6 ears of corn, you multiply 4 times the $2 to get your price, which is $8. Ending with the solution that Carmen spent $8.
Let the number of girls be g and the number of boys be b.
b = 3g
Class average = class score/class size = 17
17 = (class score) / 3g + g
68g = class score
Class score = girls score + boys score
Girls average = girls score/g
girls score = 18g
68g = 18g + boys score
boys score = 50g
Boys average = 50g/3g
= 16.7
A= 3.1 and b= 2.5 hope this helps
