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.
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.
She should move it one place to the left because there is one zero in ten so however many zeros there are in the multiple of 10 that's how many times you move it. Then, you move it left to divide and right to multiply. Hope I helped!
