Answer:

$16

Step-by-step explanation:

Answer:

Estimate: $16

Exact amount: $15.98

Step-by-step explanation:

To find the estimate amount of money she has left, we will add everything up and subtract it from $45.12.

$7.89 + $21.25 = $29.14

$45.12 - $29.14 = 15.98

Now lets round your answer to $16.  Therefore, the estimated amount that she has left is $16.   And based on the calculations above, we can see that the exact amount of money she has left is $15.98.
