The seventh-grade class earned more money in September Or October by $30,$75 or $190

Answer 1

Part A: $1.20
Part B: is actually $80 because 900 multiplied by .40 is 360 and 700 multiplied by .40 is 280. Subtract the two and it equals 80

Answer 2

$ 1.50 = x + .2x
$ 1.50 = $1.2x
$ 1.25 = x

September Price = $1.25
October Price = $1.50

Sales
September $1.25 * 900 = $1125.00
October $ 1.50 * 700 = $1050.00

7th grade earnings
September $1125 * .40 = $450
October $ 1050 * .40 = $420

Difference between September and October: $450 - $420 = $ 30.00
