2 answers:
The easiest way to answer this question is by rounding $5.99 and $7.99 to $6.00 and $8.00. Then multiply 3 by 6 and 5 by 8. 
. Now to find the exact answer, seeing as $5.99 is 1 cent away from $6.00 and $7.99 is one cent away from $8.00, we can do 
and 
, we can see that $49 is 8 cents over. From there we subtract the 8 cents from the $49 and see that the amount she spent on downloads was $48.92.

<u>Answer:</u>
Standard form of a line passing through (-2, 4) and having slope of -1/7 is x + 7y = 26
<u>Solution:</u>
Given that we need to determine standard form of a line that goes through (-2 , 4) and slope of the line is -1/7
Standard form of line passing through point ( a , b ) and having slope m is given by
(y – b) = m ( x – a) --------(1)
In our case given point is ( -2 , 4 ) and slope is -1/7 that means
a = -2 , b = 4 , m = -(1/7)
On substituting given value of a , b and m is equation (1) we get
=> 7( y - 4 ) = -x – 2
=> 7y + x = -2 + 28
=> x + 7y = 26
Hence standard form of a line passing through (-2,4) and having slope of –(1/7) is x + 7y = 26
