Step-by-step explanation:
The equation 0.5s+ 9.99=30 describes the situation.
9.99 is the fixed amount
0.5 is the cost for each song download
30 is the maximum amount spend for a month
Here 's' represents the number of songs download
0.5s+ 9.99=30 means
0.5 times the number of songs plus the fixed cost 9.99 should be equal to 30 dollars.
The solution to this equation is s=40.02.
s= 40.02 means 40 songs can be downloaded as per the budget
