Answer
Charles can buy not more than 50 songs or Charles can buy a maximum of 50 songs.
Step-by-step explanation
Let the number of songs that Charles can buy be n
Charles has $84.50 that he can spend. This means he can spend less than or equal to $84.50
He's spending this cash on music and membership for a music website.
Membership for music website = $35
Cost of one song = 99 cents = $0.99
Cost of n songs = (0.99) (n) = (0.99n) dollars
Total cost of membership for music website and n songs = (35 + 0.99n) dollars
But, this total cost has to be less than or equal to $84.50
(35 + 0.99n) ≤ 84.50
35 + 0.99n ≤ 84.50
Subtract 35 from both sides
35 + 0.99n - 35 ≤ 84.50 - 35
0.99n ≤ 49.50
Divide both sides by 0.99
(0.99n/0.99) ≤ (49.50/0.99)
n ≤ 50
This means Charles can buy not more than 50 or Charles can buy a maximum of 50 songs.
Hope this Helps!!!
