The students at Midtown Middle school sold flowers as a fundraiser in September and October. In October, they charged $1.50 for

swat32

Let the price of flowers in September be x, then (100 + 20)/100 * x = $1.50
120/100 * x = $1.50
1.2x = $1.50
x = $1.50/1.2 = $1.25
The price of flowers in September is $1.25

Total money realised in September = $1.25 x 900 = $1,125
40% earned = 0.4 x $1,125 = $450

Total money realised in October = $1.50 x 700 = $1,050
40% earned = 0.4 x $1,050 = $420

The class earned more money in September and they earned $30 more than in October.

A blueprint for a house shows the height of the house to be 3 1/4 inches. The actual house is 21 1/3 feet tall. What is the unit

Lostsunrise [7]

Answer:

6 $\frac{22}{39}$ or $\frac{256}{39}$ feet per inch

Step-by-step explanation:

Yeah. This is a question about scaling.

Basically, it's asking how many feet (in real life) are being represented by one inch in the blueprint.

You solve it by dividing the height of the actual house by the height of the blueprint. And, since the actual house is in feet, and the blueprint is in inches, your answer will be in feet per inches.

Does that help?
