Answer:
You don't have enough money for 2 downloads
Step-by-step explanation:
The cost of downloading one movie is ...
g(1) = 2·1 = 2 . . . dollars
The cost of downloading one song is ...
f(1) = (1/2)(1) +2 = 2.50 . . . dollars
Downloading 2 songs, 2 movies, or one of each will cost more than $2.50.
You don't have enough money for 2 downloads.
Account 1 = $5750 Interest 9% = $517.50
Account 2= $ 250 Interest 5% = $ 12.50
$517.50+$12.50=$350
