If A = square then add 3, B = halve then subtract 2, C = double then subtract 5, find:
4 A B C
Show answer & explanation
Correct answer: D
Explanation
A = Square and add 3
B = Halve and subtract 2
C = Double and subtract 5
Now perform the operations on 4 A B C sequentially:
4 A → 4² + 3 = 16 + 3 = 19
19 B → 19/2 − 2 = 9.5 − 2 = 7.5
7.5 C → 2 × 7.5 − 5 = 15 − 5 = 10
