Question

Nina bought a computer mouse for $9.30. She paid with a $20 bill. How much change did she get back?

A.
$11.70
B.
$10.70
C.
$9.70
D.
$29.30

Answer 1

Answer: B. 10.70

Explanation:

So we are given how much she spent and how much it costed.

So if the mouse costed $9.30 but she paid with 20 we would just subtract

9.30 - 20 = 10.7 or 10.70

(You could also check this by adding- 10.70 + 9.30 = 20 )

So she got 10.70 change back
