Question

The students at Midtown Middle school sold flowers as a fundraiser in September and October. In October, they charged $1.50 for each flower. The October price was a 20% increase of the September price. Part A What was the price of the flowers in September?

Answer 1

Answer:

Part A) $1.25

Part B) September, $30

Explanation

Part A)

Let x be the amount the flowers sold for in September.  Since the October selling price is a 20% increase, this is 0.20x.  We add this to x, the price of September, since it is an increase:

x+0.2x

This is equal to October's selling price, 1.50:

x+0.2x = 1.50

Combine like terms:

1.20x = 1.50

Divide both sides by 1.20:

1.20x/1.20 = 1.50/1.20

x = 1.25

This means the flowers sold for $1.25 in September.

Part B)

We first find out how much money they collected from selling flowers in September.  The September selling price was $1.25, and they sold 900:

1.25(900) = 1125

They earn 40% of this:

0.40(1125) = $450

They earn $450 in September.

The October selling price was $1.50, and they sold 700 flowers:

1.50(700) = 1050

They earn 40% of this:

0.40(1050) = 420

They earn $420 in October.

This means they earn more money in September, and they earned 450-420 = $30 more.
