Answer:
$9
Step-by-step explanation:
Since the question only asks for small ones, we only need to focus on 1.80 and 5. Multiple them. 1.80×5 and we get 9. 1.80×5=9
9 - (a - 7)
Note that - = -1
First, distribute - 1 to all terms within the parenthesis
-1(a - 7) = -a + 7
9 - a + 7
Combine like terms
9 + 7 = 16
-a + 16, or A. 16 - a is your answer
