Equality Properties

Step-by-step explanation:

Step 1: Define Equation

6n + 7 = 55

Step 2: Solve for n

Subtract 7 on both sides: 6n = 48
Divide 6 on both sides: n = 8

Step 3: Check

Plug in n into the original equation to verify it's a solution.

Substitute in n: 6(8) + 7 = 55
Multiply: 48 + 7 = 55
Add: 55 = 55

Here we see that 55 does indeed equal 55.

∴ n = 8 is a solution of the equation.

He is paid a commission of 9 percent of his first $6,000 in sales during the month and 14 percent on all sales over $6,000. What

Agata [3.3K]

Answer:

$1,956.80

Step-by-step explanation:

For amounts over $6000, the commission can be computed as ...

0.14s -300 . . . . . . for sales (s) ≥ 6000

So, for $16,120 in sales, the commission is ...

0.14×$16,120 -300 = $2,256.80 -300 = $1,956.80

The commission schedule suggests that for larger amounts, you divide the problem into two parts: calculate the commission on $6000, and separately calculate the commission on the amount over $6000.

0.14(s -6000) + 0.09(6000)

= 0.14s - 0.14·6000 +0.09·6000

= 0.14s -300 . . . . the formula used above for s ≥ 6000
