Answer:

real number

Step-by-step explanation:

Hi! -4 is a real number because imaginary numbers are characterized as i= sqrt -1

If you see a number with an i in it, then it is imaginary. In this case, however, we have a real number.

I hope this helps!

Becca has a balance of $22.90 at the beginning of May for clothes. Her allotment for the month is $50.00. She buys a two new out
a_sh-v [17]

Add the balance and allotment:

22.90 + 50.00 = 72.90

This is how much she can actually spend.

She spent 85.50.

Subtract the two:

85.50 - 72.90 = 12.60

Since she spent more than she actually could be balance would be a negative number.

The balance would be  - $12.60
