Writing A farmer recently sold a large plot of land. The sale decreased his total acreage by 5%. Let t 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?
А.
5t
t－0.05t
C.
1- 5t
0.05t
E.
0.95t - 0.05t
F. 0.95t
The correct answer is:
B. t - 0.05t (expression to find the new acreage)
And
F. 0.95t (expression to find the new acreage)
Two ways to find the new acreage:
1. Subtract 0.05 times the original acreage (t) from the original acreage. This can be represented by the expression t - 0.05t.
2. Multiply the original acreage (t) by 0.95, which represents 95% of the original acreage. This can be represented by the expression 0.95t.
