The first house lot was 250 feet by 300 feet and the second house lot was 350 feet by 400 feet. the cost per square foot to purchase a lot was $5. how much is the total purchase price for buying both lots?

$1075000 is the cost to purchase both the lots.

Step-by-step explanation:

The first house lot was 250 feet by 300 feet.

If the cost of per square feet to purchase a lot was $5 then cost of first lot will be = 250×300×5 = $375000

Second house lot was 350 feet by 400 feet.

So to purchase this lot with $5 per square feet = 350×400×5 = $700000

Now total purchase price for buying both the lots will be = $375000 + $700000 = $1075000

Therefore, $1075000 is the cost to purchase both the lots.

you can't solve x because it is 2 linear equation and you only have one equation

b.-4 units

all you   do is count how many times you move
