Question 1153552: Hi
This is exactly as it appears in the textbook. Josie needs a new computer and has saved $1500.00. She decided to wait for the end of year sale where she was promised a 15 percent discount and a further 3 percent off if she paid cash.
What is the maximum value to the dollar of a full priced computer she can afford if she pays cash.
What is the difference between the full price computer she can afford with cash and of a computer she paid by card.
Thanks

You can put this solution on YOUR website! .
Let x be the maximum value of the full priced computer she can afford if she pays cash
(i.e. exactly the unknown value under the question).
Then the equation for x, from the given condition, is
0.97*(0.85x) = 1500 dollars, (1)
where 0.85 = 1-0.15 and 0.97 = 1-0.03.
From equation (1)
x =  = 1819.28 dollars. ANSWER to Q1
The answer to the second question is
difference = 1819.28 -  = 1819.28 - 1764.71 = 54.57 dollars. ANSWER to Q2

The "after-solution" notice.
The problem's formulation in THIS post ( "exactly as in the textbook" ) is correct and meaningful.
The problem's formulation in your previous post was nonsensical.
The conclusion, the diagnosis and the advise for the future :
if you do not understand the subject,
do not make your arbitrary changes in the original formulations.
Post them "word-in-word", as is.

In one of my previous posts, I wrote once that, according to my feeling,
there is a "visitor" in this forum at the opposite end of the Internet,
who permanently and intently corrupts every post he submits.
It looks like that my suggestion was correct, and now I detected and discovered this visitor.
