Chapter 1.1, Problem 35PPE

To determine

Find the expression that gives the value in dollars of $d\mathrm{dimes}$ .

Answer to Problem 35PPE

  $\left(A\right)0.10d$

Explanation of Solution

Given information:

  $\left(A\right)0.10d\left(B\right)0.10+d\left(C\right)\frac{0.10}{d}\left(D\right)10d$

Calculation:

Here, we have to find the expression that gives the value in dollars of $d\mathrm{dimes}$ :

  $\begin{array}{l}1\mathrm{dime}=\frac{1}{10}dollars\\ d\mathrm{dimes}=d\times \frac{1}{10}dollars\\ d\mathrm{dimes}=d\times 1.10dollars\\ d\mathrm{dimes}=0.10ddollars\end{array}$

Thus, the expression is $0.10d$

Hence, the correct answer is $option\left(A\right)$ .
