A retailer sells a refrigerator for a list price of $1,200. The retailers cost was $850. What is the percentage of the markup?

matrenka [14]

Answer:

41%

Step-by-step explanation:

1200-850=350

350 is the markup, now we need the percentage

the orginal price was 850 so we just need to divide 350 by 850

we get 0.4117...

convert that to a percentage and we have 41% markup

Graph the solution of the inequality on a number line. x − (5 − 3x) ≤ 2x − 1

egoroff_w [7]

Answer:

x ≤ 2

Step-by-step explanation:

x − (5 − 3x) ≤ 2x − 1
x - 5 + 3x ≤ 2x - 1
4x - 5 ≤ 2x - 1
4x - 2x ≤ 5 - 1
2x ≤ 4
x ≤ 2 or x ∈ (- oo, 2]

The graph includes all point to the left from point 2, same point included

I need help on my warm up!! pls thx!

Step-by-step explanation:

$\tt{30.16 = 17.56 + 5x}$

Swap the sides of the equation :

⤑ $\tt{17.56 + 5x = 30.16}$

We want to remove the 17.56 first.

Since the original equation is 17.56 , we are going to use the opposite operation and subtract 17.56 from both sides :

⤑ $\tt{5x + 17.56 - 17.56 = 30.16 - 17.56}$

Simplify. 17.56 - 17.56 = 0 on the left. 30.16 - 17.36 = 12.6 on the right.

⤑ $\tt{5x = 12.6}$

Then, we need to think about how to remove the coefficient 5. Since the opposite of multiplication is division , I am going to divide both sides by 5.

⤑ $\tt{ \frac{5x}{5} = \frac{12.6}{5}}$

Simplify. 5/5 = 1 on the left and 12.6/5 = 2.52 on the right. So, Our answer is x = 2.52.

$\pink{ \boxed{ \boxed { \tt{Our \: final \: answer : \underline{ \underline{ \bold{ \tt{x = 2.52}}}}}}}}$

Hope I helped ! ♡

Have a wonderful day / night ! ツ
