Answer:

Explanation:

If x is increased by 50%, it means that the amount by which x is increased is

50/100 × x = 0.5 × x = 0.5x

The new value of x would be

x + 0.5x = 1.5x

If the new value is further decreased by 30%, it means that the amount by which it was decreased is

30/100 × 1.5x = 0.3 × 1.5x = 0.45x

The new value of x would be

1.5x - 0.45x = 1.05x

Therefore, the result is 1.05x
