Answer:

$\text{A. }y=1.30x+1.50$

Step-by-step explanation:

The two ringtones will cost her a total of $0.75\cdot 2=1.50$ and is a fixed amount. The relationship between the cost and number of songs only is $y=1.30x$ and therefore the answer is $\boxed{\text{A. }y=1.30x+1.50}$ . You can also directly find the answer by finding the y-intercept (in this case $1.50$ ), as no other answer choices include the term $1.50$ , so A must be the correct answer.
