Answer:
It will take 100 songs for the monthly price of Napster to cost the same as iTunes.
Step-by-step explanation:
Let's create two equations to represent iTunes (T(d)) and Napster (N(d)):
T(d)=0.99d
N(d)=0.89d+10
In order for us to find when the two prices will be the same, let's set the equations equal to each other and solve for x:
0.99d=0.89d+10
0.1d=10
d=100
Answer:
7/18
Step-by-step explanation:
-4 × -7
9 × 8
28/72, which would simplify to 7/18
Subtract 2 from 20. Then, divide 18 by 3 and that should give you 6.
