Answer:
169 pairs of boots
Explanation:
Let's represent the number of pairs of boots on display originally as "x".
When the store sold 29 pairs of boots, the number of pairs remaining on display was "x - 29".
Then, the store brought out another 34 pairs from the stock room, so the total number of pairs on display became:
(x - 29) + 34
Simplifying this expression, we get:
x + 5
We know that the total number of pairs of boots on display after bringing out the extra 34 pairs is 174. Therefore, we can write the equation:
x + 5 = 174
Solving for x, we get:
x = 174 - 5 = 169
Therefore, there were originally 169 pairs of boots on display in the store.
