Answer: [tex]\$10.7[/tex]
Step-by-step explanation:
Given
Nina bought a computer mouse for $9.30
She paid a $20 dollar bill
The money she received is the difference between what is paid and the cost of the mouse i.e.
[tex]\Rightarrow 20-9.3\\\Rightarrow \$10.7[/tex]
Therefore, she gets [tex]\$10.7[/tex] after deductions.
