To determine

Towrite: The equivalent expression for the given expression.

Answer to Problem 51PFA

B. $1.35n-0.75$

Explanation of Solution

Given:

The expression $0.25\left(5n-3\right)+0.10n$ .

Calculation:

Simplify the given expression as follows:

  $\begin{array}{c}0.25\left(5n-3\right)+0.10n=0.25\cdot 5n-0.25\cdot 3+0.10n\left(\text{Distribute 0}\text{.25 over parenthesis}\right)\\ =1.25n-0.75+0.10n\\ =1.35n-0.75\left(\text{Combine the like terms}\right)\end{array}$

Therefore, the correct option for the equivalent expression is B. $1.35n-0.75$ .
