Rodger gets $40 per day as wages and $4.50 as commission for ever paid of shoes he sells in a day. His daily earning goal is $11

Charra [1.4K]

112 = 40 + 4.50p

Kryger [21]

Answer:

The value of variable r in the equation $10r+4=8$ is $\mathbf{r=0.4}$

Step-by-step explanation:

We need to find the value of variable r in the equation $10r+4=8$

Step 1: Write the equation

$10r+4=8$

Step 2: Subtract 4 on both sides

$10r+4-4=8-4\\10r=4$

Step 3: Divide both sides by 4

$\frac{10r}{10}=\frac{4}{10}\\r=0.4$

So, The value of variable r in the equation $10r+4=8$ is $\mathbf{r=0.4}$
