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

Naddik [55]
Hey there!

Since 2 goes into 8, you would simplify. You would get 1 inch and 4 miles. Next, set up a ratio. The ratio is 1 inch: 4 miles. So for every inch on the map, there is 4 miles.

I hope this helps!
