Question

In October flowers cost $1.50 each. The October price was a 20% increase of the September price. What was the price of of the flowers in September

Answer 1

Hey there!!

Let's write $1.5 as 15 / 10

15/10 = 3/2

$3/2

October price = $3/2

Let's take September price as ' x '

If we take a look at the question, we know

October price = 20% of September + September price

20% = 20/100 = 1/5

Of = multiplication

Plug in the values

3/2 = x/5 + x

LCM = 5

3/2 = 6x / 5

Multiplying by 5 on both sides

15/2 = 6x

Dividing by 6 on both sides

15/2 / ( 6 ) = x

15/2 × 1/6 = x

15/12 = x

15/12 = $1.25

The price in September = $1.25

Hope my answer helps!

Answer 2

Let p represent the price of the flowers in Sept.

The price in Oct. was then p  plus 0.20p, or 1.20p = $1.50.

                                $1.50

Solving for p,  p = ------------ = $1.25

                                1.20

One would have paid $1.25 per flower in Sept. and 20% more, or $1.50, in October.
