Solve the following absolute value equations. Show the solution set and check your answers. |0.3-3/5k|-0.4=1.2

Answer:

**The equation is not clear, so I have provided both options**

<h3><u>Option 1</u></h3>

$\left|0.3-\dfrac{3}{5}k\right|-0.4=1.2$

$\implies \left|0.3-\dfrac{3}{5}k\right|=1.6$

<u>Solution 1</u>

$\implies 0.3-\dfrac{3}{5}k=1.6$

$\implies -\dfrac{3}{5}k=1.3$

$\implies k=-\dfrac{13}{6}$

<u>Solution 2</u>

$\implies -(0.3-\dfrac{3}{5}k)=1.6$

$\implies -0.3+\dfrac{3}{5}k=1.6$

$\implies \dfrac{3}{5}k=1.9$

$\implies k=\dfrac{19}{6}$

<h3><u>Option 2</u></h3>

$\left|0.3-\dfrac{3}{5k}\right|-0.4=1.2$

$\implies \left|0.3-\dfrac{3}{5k}\right|=1.6$

<u>Solution 1</u>

$\implies 0.3-\dfrac{3}{5k}=1.6$

$\implies -\dfrac{3}{5k}=1.3$

$\implies -3=6.5k$

$\implies k=-\dfrac{6}{13}$

<u>Solution 2</u>

$\implies -(0.3-\dfrac{3}{5k})=1.6$

$\implies -0.3+\dfrac{3}{5k}=1.6$

$\implies \dfrac{3}{5k}=1.9$

$\implies 3=9.5k$

$\implies k=\dfrac{6}{19}$

The sales tax for an item was $24.50 and it cost $490 before tax.

Ymorist [56]

The sales tax rate is 5%.

Step-by-step explanation:

Given,

Sales tax for an item = $24.50

Cost of item before tax = $490

Sales tax rate = $\frac{Sales\ tax}{Cost\ of\ item}*100\\$

$Sales\ tax\ rate=\frac{24.50}{490}*100\\\\Sales\ tax\ rate=\frac{2450}{490}\\\\Sales\ tax\ rate=5\%$

The sales tax rate is 5%.
