OPTION D: Identity property of Addition.

Step-by-step explanation:

In addition, the identity element is the element, 'e' which when added to any element in the set does not alter the value.

We have, for an element 'a',

                                       a + e = a = e + a

So, here, 0 is added to -7 and the value is not changed.

i.e., - 7 + 0 = - 7

Hence, 0 is the identity element of addition.

Note that 1 is the identity element of multiplication.

a - base

b - exponent

so,

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
