The ribys spent 5625 for 4.5 acres of land find the price per acre

We can find the price per arc by dividing the total price by the amount of arc.
so in this case
5625 is the total money spent
and 4.5 is what they get when spending that amount of money
5625 / 4.5
= 1250
The price per arc is $1250
therefore, the answer is $1250. 

It's easy. What you need to do is divide the amount of money spent by the amount of acres bought. So it's $5,625 divided by 4.5 acres, which would look like $5,625/4.5, which equals $1,250 spent of each acre owned.
