Which of the following options is the estimation to nearest tens of the simplification of given equation?  73 + 89 – 13 x 2 + 38

A. 150
B. 170
C. 180
D. 200

Answer: B

Solution:
To solve the equation according to the order of operations (PEMDAS/BODMAS), which prioritizes multiplication and division before addition and subtraction, we have:

73 + 89 – 13 x 2 + 38

= 73 + 89 – 26 + 38

= 174

The estimation of 174 to the nearest tens is 170.
So, the correct answer from the given options is 170.
