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

Answer:

Cost of shelves = $148.50

Step-by-step explanation:

Measure of each shelf= $275\ cm\ = \frac{275}{100} \ m\ =2.75 \ m$

Measure of 4 shelves together= $4\times2.75\ m\ = 11 m$

Cost of lumber  = $$13.50$ per meter

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

$\\=11\times13.50$=$148.50
