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?
Answer:
$1.25
September
$30
Step-by-step explanation:
Let's take this a step a time.
First we need to find how much the price of the flowers were in September.
We know that each flower cost $1.50 on October.
The October price was a 20% increase of the September price.
To calculate for the price of the flowers on September, we can solve it like this:
Let x = Price during September
1.2x = 1.50
We used 1.2 because the price of $1.50 is 120% of the original price.
Now we divide both sides by 1.2 to find x.
x = 1.25
The price of the flowers during September was $1.25 each.
Now the 7th grade class earned 40% of the selling price of each flower.
40% = 0.40
To find how much they made on each month, we simply multiply the percentage to the price and the number of flowers sold.
September = 0.40 x 1.25 x 900
September = 0.5 x 900
September = $450
Now for October.
October = 0.40 x 1.50 x 700
October = 0.6 x 700
October = $420
The 7th Graders earned more on September.
They earned $30 more on September than October.
Answer:
cylinder: V = π R² H
Volume = (pi) x (square of the radius) x (height of the cylinder)
square of the radius means ( R x R )
sphere: V = (4/3) π R³
Volume = (4/3) x (π) x (cube of the radius)
cube of the radius means ( R x R x R )
To me they look all answered...
