Chapter 2: Q. 139 (page 230)

In the following exercise, solve each equation.
$c - 0.3 c = 37.50$

Short Answer

Expert verified

The solution of the equation is $c = 51 .$

Step by step solution

Step 1. Given information

$\begin{array}{l} Thegivenequationis c - 0.3 c = 35.70. \\ Wehavetosolvethegivenequation. \end{array}$

Step 2. Simplify

$\begin{array}{l} Now, \\ \Rightarrow c - 0.3 c = 35.70 \\ \Rightarrow 0.7 c = 35.70 [Simplifyeachside] \\ \Rightarrow \frac{7 c}{10} = \frac{3570}{100} [Writethedecimalformintofractionform] \\ \Rightarrow 10 \times \frac{7 c}{10} = 10 \times \frac{3570}{100} [Multiplybothsidesby10] \\ \Rightarrow 7 c = 357 \\ \Rightarrow \frac{7 c}{7} = \frac{357}{7} [Dividebothsidesby 7] \\ \Rightarrow c = 51 \end{array}$
