Answer:
$13.04
Step-by-step explanation:
First, multiply 16.89 by 1.2, 0.6, and 1.0725. You should get a weird number on your calculator saying 13.042458, but just round 2 to the 4 ( 4 stays the same) and remove all the other numbers to get $13.04
# 2 the you are on the right one
2
10a² : 5a² = 10 : 5 = 2
Negative
It would be -1.3. Because you know? You add?
