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

x - a = = 5 ( add a to both sides )
x = a - 5
Given : Big cargo box measures 12m x 6m x 5m
Volume of the Box : Length x Breadth x Height
Volume of the Big cargo box : (12 × 6 × 5) = 360 m³
We know that : 1m = 100cm
Volume of the Big cargo box : 360 (100cm)³
Volume of the Big cargo box : 360 × 100³ × cm³
Given : Small box measures 40cm x 25cm x 10cm
Volume of the Small box : (40 × 25 × 10) = 10000 cm³
Small boxes which can be put into Big cargo box :
