Answer:
$45
Step-by-step explanation:
For calculating the magnitude of quantities we use the absolute value. The absolute |x| of a number x is value of x regardless to its sign. So we will have |x| = x if x is positive, and |x| = −x if x is negative, which means that our result will be always positive.
This means that the magnitude of the amount overdrawn is |-$45|=$45
