Ineed it a laptop computer has a selling price of $800. this includes a 20% mark up. the computer is also being offered at a discount of 20%. a customer thinks that the seller is going to break even given this information. is the customer correct explain your reasoning? a. what was the price of the laptop before the markup? b. what is the discounted price of the laptop?

 customer is incorrect  

Step-by-step explanation:

I am working this from b first

b $800 x .20 (20%) = $160 discount

$800 - $160 = $640 customers price

the price of the computer after the 20% discount would be $640

a  customer thinks seller is going to break even  this is not true

$640 (customer cost after discount) x .20 (20% discount) =$ 128

$640 + $128 = $768

Cost of the laptop before the 20% markup is $667.67

$666.67 x .20 = $133.33

$666.67 + $133.33 = $800

$768 ≠ $667.67

answer: 2 and 1

step-by-step explanation: got this question

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
