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.
(b) Explain what the half in the quotient refers to in your model.
please help u get 24 points
The result of division (1 + 1/2) by (1/3) has been solved as the quotient is 4 + 1/2.
The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
As per the given,
1 1/2 divided by 1/3= 4 1/2.
(1 + 1/2)/(1/3) = 4 + 1/2
(a)
In the division of two fractions the numerator and denominator will interchange to come in multiplication as,
⇒ (1 + 1/2) x (3/1)
⇒ 3 + 3/2
⇒ 3 + 1 + 1/2
⇒ 4 + 1/2
(b)
The half in the quotient refers that the number 1 1/2 is not completely divisible.
Hence "The result of division (1 + 1/2) by (1/3) has been solved as the quotient is 4 + 1/2".
