Answer:
Its asking what x 2=1 it would be
Step-by-step explanation: 0.5 or 1/2
if one customer shows up, and she buys one song, that's $1.29, if she doesn't buy anymore, then that's the charge.
the first song is always at a full price, and after that, to encourage buying, the next ones are just 99 cents, let's see how it goes after a few songs purchases.
1 song.........................$1.29
2 songs.......................$1.29 + 0.99(2)
3 songs.......................$1.29 + 0.99(3)
4 songs.......................$1.29 + 0.99(4)
c songs.......................$1.29 + 0.99(c)
s(c) = 1.29 + 0.99c.
Answer C is correct because 2×(4×305) is the same as (2×4)×305 and 2×4=8.
Answers: a = 49
b = 10
c = 105
The answer is x=-6 and y= 1
