Answer 2

What kind of help do you need?
What is the regular price of this TV?
If Target cuts that price by 35%, how much will a purchaser save on this TV?

Answer 3

For the first question, I put Target.

Answer 4

Please discuss why you chose Target over Best Buy.

Answer 5

Okay, so for Target, I did: \[$415 \times 0.35 = $145.25\]
then subtracted:
\[$415 - $145 = $269.75\]

For Best Buy:
\[$415 - $120 = $295\]

Then i decided that:
\[$269. 75 < $295\]

Answer 13

Sounds like this lucky girl gets 3 TVs for only $597.25. Is that your interpretation, or do you think $597.25 is the sale price for EACH of the 3 TVs?

Answer 14

i did:
65% of ____ = 597.25
\[\frac{ is }{ of }= \frac{ % }{ 100 }\]
i replaced those:
\[\frac{ 597.25 }{ x } = \frac{ 13 }{ 20 }\]

i then got:
11945=13x

x = 918.846 ~ 918.85

since it is i believe that 918.85 is the total regular price, that's why divided by 3 and got 306.282 ~ $306.28

Answer 15

Answer 16

\[\frac{ is }{ of }=\frac{ percent }{ 100 }\]

Answer 17

We could check your result as follows: Multiply your "regular price" figure by 0.65 and see whether or not that results in $597.25. If you do get that result, you can assume that your answer is correct.

Answer 18

Thanks @mathmale

Answer 19

Your "regular price" amount is $918.85.
Multiply that by 0.65: 0.65($918.85)=$597.25.

What does this result tell you?
