Mikayla found a website that allows her to download songs for $1.30 each and ringtones for $0.75 each. Mikayla downloads x songs and 2 ringtones.
Which equation can be used to find y, the total cost that Mikayla must pay?
Responses
A y = 1.50x + 1.30y = 1.50 x + 1.30
B y = 0.75x + 2.60y = 0.75 x + 2.60
C y = 1.30x + 0.75y = 1.30 x + 0.75
D y = 1.30x + 1.50
B y = 0.75x + 2.60
