C because when you add 2 in one column you keep adding three to the other
Jayla payed $36.90 i got this because i multiplied 3 times 15 and got 45 then i did .18 times 45 which is 8.1 (8.1 is how much will be taken off) and then i subtracted 45-8.1 and got $36.90
It would be 75 cents per song, I hope you get a good grade!
