Question

Hello everybody!! Can somebody help me with this?

"The expression 937(1+x) gives the markup price of a computer, where x is the percent of the markup written in decimal form.

Which part of the expression represents the percent, in decimal form, of the initial price that is being paid?"

Is it (1+x) ? Or just x ? I'm not understanding too well.

Answer 1

@Unavailabilityy
She had solve this question before :D

Answer 2

Don't overthink it. The only reason the 1 is there is to retain the value of 937.

For example, if the markup was equal to 5%, we would write:
937(1+0.05)=983.85

If we didn't have the 1 there, it wouldn't make sense!
937(0.05)=46.85

Answer 3

?

Answer 4

Ur question Una XD

Answer 5

So @Aveline , if we have this question

"The expression 0.07x+(x−300) models the final price of a television set with an instant rebate in a state that charges a sales tax.

Enter the expression in the box that represents the price of the television set after the instant rebate is applied and before the tax is applied."

That's 300? Because I answered it as (x-300).

Answer 6

And @Unavailabilityy , the reason you were tagged is because @Kevin said you have this question before, so maybe you can help out, as well?

Answer 7

you got it!

Answer 8

Hmm, I can try :)

Answer 9

The expression that represents the TV with the instant rebate is (x-300).
The 0.07x is the sales tax (added to the overall total) The -300 shows that the TV is 300 dollars off (the rebate)
