The output value of a factory increases by 20% every year. If the output value in the first year is 10000 yuan, what is the output value in the second year? When a = 20000, calculate the output value in the second year Output value

The output value of a factory increases by 20% every year. If the output value in the first year is 10000 yuan, what is the output value in the second year? When a = 20000, calculate the output value in the second year Output value

a+a*20%
When a = 20000, 20000 + 20000 * 20% = 24000

The output value of a factory in January was 500000 yuan. After adopting advanced technology, the total output value in the first quarter was 1.82 million yuan. What is the average monthly growth rate in February and March?

Suppose that the average monthly growth rate in February and March is x, 50 + 50 (1 + x) + 50 (1 + x) 2 = 182, 50 + 50 + 50x + 50 + 100x + 50x2 = 182, 50x2 + 150x-32 = 0, (5x + 16) (10x-2) = 0, ｜ 5x + 16 = 0, 10x-2 = 0, and the solution is X1 = - 3.2 (negative value, rounding off), X2 = 0.2 = 20%

The output value of a factory in April is 500000 yuan. If the output value in the second quarter is 320000 yuan more than that in April due to the same percentage growth in May and June, the average growth rate of the output value in May and June is______
