Answer:
The cost of homes per square foot differs in different part of the United states. The cost of homes per square foot is gotten by using the formula:
cost of homes per square foot = Cost of apartment / area of apartment
1) Cost of apartment = $540000, area of apartment = 450 ft²
cost of homes per square foot = Cost of apartment / area of apartment = $540000/ 450 ft² = $1200 / ft²
2) cost of homes per square foot = $110/ ft², area of apartment = 2100 ft²
cost of homes per square foot = Cost of apartment / area of apartment
$110 / ft² = Cost of apartment / 2100 ft²
Cost of apartment = $110 / ft² × 2100 ft² = $231000

If x is the number of berries you can buy with 1 dollar,
1 pound of blueberries = $4.00
x pound of berries = $1.00
Lets set up a proportion- because these are directly proportional- when there is more pounds of berries, it will cost more.

Cross multiply
4x=1
Divide both sides by 4 to isolate x
x=1/4 or $0.25
