A farmer recently sold a large plot of land. The sale decreased his total acreage by 10%. Let x be the original acreage. Find two equivalent expressions that will give the new acreage. Use pencil and paper. Use the expressions to describe two ways to find the new acreage. Which two expressions will give the new acreage
The original acreage is x.
If the sale decreased his total acreage by 10%, then the new acreage would be (100% - 10%) * x = 90% * x.
Therefore, one expression that gives the new acreage is 0.9x.
Another equivalent expression is x - 0.1x, which also gives the new acreage.
To find the new acreage using 0.9x, you can simply multiply the original acreage by 0.9.
To find the new acreage using x - 0.1x, you can subtract 10% of the original acreage from the original acreage.
