Your school is having a Mum fundraiser, and your teacher has asked you to determine the retail cost for each Mum. You are only growing 6in Mums and will be covering them in a foil sleeve and adding a bow. The teacher told you plants have a 3x markup, whereas nonplant products have a 2x markup. You will also need to add an additional 20% to this cost to factor in labor.

The school has a $3.20 wholesale cost in each of the Mums.

Ribbon is $10.00 for a 100-yard roll at the wholesale store. It takes 2 yards to make 1 bow.

Foil sleeves are $0.60 each at the wholesale store.

What is the total RETAIL cost of one Mum?

• $9.60

• $11.20

• $13.44

• $18.56

Answer explanation

$3.20 wholesale cost for Mum x 3 mark up = $9.60

Ribbon is $10.00 for a 100-yard roll = $0.10 per yard x 2 = $0.20 per bow x 2 mark up = $0.40

Foil sleeves are $0.60 x 2 mark up = $1.20

$9.60 + $0.40 + $1.20 = $11.20 x .20 = $2.24 labor

$11.20 + $2.24 = $13.44 Total Retail Cost

Sunny Days Greenhouses has decided to catch rainwater to supplement some of the watering needed for their TWO largest greenhouses. They have purchased commercial rain barrels that are 6 feet tall and have a diameter of 4 feet to collect the rainwater. Due to the length, each greenhouse will require 6 barrels. How many gallons of water can be collected in all the rain barrels?

• 563.69 gallons

• 6,764.31 gallons

• 3,382.14 gallons

• 1,234 gallons

Answer explanation

Diameter = 4 ft, Height = 6 ft, and Radius = 2 ft

V = חr²h

V = 3.14(2²) (6)

V = 3.14 (4) (6)

V = 75.36 Ft³

7.48 X 75.3 = 563.69 gallons

563.69 gallons X 12 (6 per greenhouse x 2 greenhouses) = 6,764.31 gallons

You are ordering potting soil for your greenhouse’s spring crops. Your plans are to purchase potting soil by the bag. You need enough potting soil to fill the following number of containers:

35 (8” baskets with saucers),

75 (10” baskets with saucers),

250 (4” square pots),

425 (6” azalea pots),

120 (8” standard pots).

Use the following table to arrive at the number of bags of potting soil that must be ordered.

• 8 bags

• 12 bags

• 18 bags

• 23 bags

Answer explanation

35 8” baskets with saucers / 26 = 1.35 bags

75 10” baskets with saucers / 14 = 5.35 bags

250 4” square pots / 130 = 1.92 bags

425 6” azalea pots / 53 = 8.02 bags

120 8” standard pots / 20 = 6 bags

1.35 + 5.35 + 1.92 + 8.02 + 6 = 22.64 or 23 bags
