Answer:
$32.80
Step-by-step explanation:
Let f be the cost of a file, then a storybook costs 3f ( 3 times as much )
Then the difference in cost is
3f - f = 16.40, that is
2f = 16.40 ( divide both sides by 2 )
f = 8.20
The cost of a file is $8.20 and the cost of a storybook is 3 × $8.20 = $24.60
The total cost of the 2 items = $8.20 + $24.60 = $32.80
That A=D, F=F (obviously), and B=E.
