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?

Part B:
The seventh-grade class earned 40% of the selling price of each flower.

In September, they sold 900 flowers.
In October, they sold 700 flowers.

Did they earn more money in September or October?

How much more?

please help

Answer 1

I would use the idea of:
whole*percent/100=part

Answer 2

The 1.50 is the part, since that it has been increased by 20%.

Answer 3

so 1.50 is A

Answer 4

No, 1.50 is the price in October. We are looking for the price in September.

Answer 5

Before it was increased by 20%.

Answer 6

oh

Answer 7

So, increasing by 20% is 120%, since 100% is what you have so far + 20% more.

Answer 8

So, the formula is
1.50 = 120/100*whole

Answer 9

And we need to solve for the whole. :)

Answer 10

Make sense?

Answer 11

yes

Answer 12

:) What do you get for the whole?

Answer 13

i got 1.70

Answer 14

Hm, that's not what I got. How did you get that?

Answer 15

i saw 20% so i thought 20 cents

Answer 16

Oh, ok. That would only be the case if the price was 1.00.

Answer 17

Also, we aren't adding 20% to this number. We are trying to find the number that we are adding 20% to that makes 1.50

Answer 18

hold on ill just figure it out myself

Answer 19

Ok, sounds good.

Answer 20

But I already gave you the formula. Just solve for "whole"

Answer 21

\[9+10=19\]

Answer 22

Yes, that is true, but I don't see how it is applicable to this problem.

Answer 23

it's not
