If 1 additional song costs $0.59, then there would be 26 additional songs downloaded. Because $15.34 divided by $0.59 is 26.
Let x be the number of songs downloaded.
x = 28 + (15.34/0.59)
x = 28 + (26)
x = 54
You have 54 songs downloaded on your tablet.
Hope this helps :)
Recall that
, which is to say
has period
. This in turn means that
will have the same solutions as
for any integer
. So the general solution to the first case is
where
is any integer.
On the other hand,
but
for any value of
, so this equation has no (real) solutions for
.
Answer:
$15.98
Step-by-step explanation:
25% off means it is 75% of its normal cost
0.75 x 20 = 15
The scarf is $15 after 25% discount. Then we calculate its final cost after tax:
6.5% = 0.065
1.065 x 15 = 15.975 which rounds to $15.98
3.75X10^5 Is the answer, check it in your calculator just to be sure!
