Question

Each of four shelves in a bookcase measures 275 cm. Find the cost of the shelves when the price of lumber is $13.50 per meter.

Answer 1

Cost of shelves = $148.50

Explanation:

Measure of each shelf=
`275\ cm\ = (275)/(100) \ m\ =2.75 \ m`

Measure of 4 shelves together=
`4*2.75\ m\ = 11 m`

Cost of lumber = $
`13.50` per meter

∴ Cost of the shelves = Measure in meters x Cost of lumber per meter

`\\=11*13.50`=$148.50
