Problema Solution

You have been hired to build a small enclosed garden for a customer. Based on a do-it-yourself guide from a gardening magazine, you need the following materials:

• Four 8 ft. × 6 in. × 6 in. wooden beams

• Twelve bags of potting soil

• Two bags of fertilizer

• One watering hose

The beams cost $15.00 per cubic foot, one bag of potting soil costs $12.25, one bag of fertilizer costs $21.50, and the watering hose costs $55.00. Sales tax is 5.5%. What is the total cost, including tax, of the materials needed to build the garden?

1 ft = 12 in

6 in = 1/2 ft

The volume of the wooden beams in ft^3 is:

V = 8 * (1/2) * (1/2)

V = 2 ft^3

2 ft^3 of wooden beams costs: 2*$15 = $30

12 bags of potting soil cost: 12*12.25 = $147

2 bags of fertilizer cost: 2*21.50 = $43

1 watering hose: $55

The total cost including taxes is:

1.055*(30 + 147 + 43 + 55) = $290.13
