The Lynn’s family bought a house for $75,300 a few years later they sold the house for $80,250 how much greater was the selling

Zepler [3.9K]

Buying price: $75,300

Selling price: $80,250

You want to find out how much more the selling price was when compared to the buying price.

To find the difference in prices, simply subtract the selling price with the buying price.

$80,250 (buying price) - $75,300 (selling price) = $4,950 (price difference)

The selling price is greater than the buying price of the house by $4,950

A painting is 2 in tall and 3 in wide. If it is enlarged to a width of 15 in then how tall will it be?

vekshin1

Answer:

10 in

Step-by-step explanation:

Old proportions:

2 x 3

New proportions

h x 15

Assuming the painting has been increased by a constant scale factor.

Where x is the unknown scale factor, and h is the height after it has been enlarged.

$3 * x = 15\\2 * x = h$

Rearrange second equation:

$3 * x = 15\\x =\frac{h}{2}$

Substitute:

$3*\frac{h}{2} =15\\\frac{h}{2}=5\\h=10$
