D Correct answer
Explanation

Approximating the values: 90% of 700 is 630, and 50% of 1000 is 500. Adding these gives 1130, and subtracting 170 results in 960.

AI explanation

We round the values to estimate the result, giving the expression 90% of 700 + 50% of 1000 - 170. This calculates to 630 + 500 - 170. Adding and subtracting these values results in 1130 - 170, which equals 960.
