The students at midtown middle school so flowers as a fundraiser in september and october they charged $1.50 for each flower october price was a 20% increase of the september price

Let the price of flowers in September be x, then (100 + 20)/100 * x = $1.50

120/100 * x = $1.50

1.2x = $1.50

x = $1.50/1.2 = $1.25

The price of flowers in September is $1.25

Total money realised in September = $1.25 x 900 = $1,125

40% earned = 0.4 x $1,125 = $450

Total money realised in October = $1.50 x 700 = $1,050

40% earned = 0.4 x $1,050 = $420

The class earned more money in September and they earned $30 more than in October.
