Answer: t - 0.1t and 0.9t
Step-by-step explanation:
Let the original acreage be represented by t.
Since there was a sale which ended up reducing the acreage by 10%, the expression for the new acreage will be:
= t - (10% × t)
= t - (0.1 × t)
= t - 0.1t
= 0.9t
Therefore, the equivalent expressions will be "t - 0.1t" and 0.9t
