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.

Answer:
60=3/4
x=4/4
4/4÷1/4
4/4*4/1
4/1*1/1
4/1
4
3/4=12 because if 1/4 is 4 then 3/4 is 12
60=12
60÷12=5
5*4/20
60+20=80

Defining variables
let n1 be the first number
n2 be the 2nd number
add them together, you get 218
n1+n2 =218
n1 is 47 less than n2
n1=n2-47
do some substitution
n2-47 +n2 = 218
solve for n2
then use n2 to figure out n1
