Question

How did the tempicher change if at first it increased by 5% and then increased by 20 percent

Answer 1

Increasing a number by 5% and then by 20% is the same as increasing the original number by 26%.

Explanation:

Take a number, x.

Now increase it by 5%.

1.05x

Now increase it by 20%.

1.2 * 1.05x = 1.26x

1.26x = 126% of x = 100% of x + 26% of x

100% of x is the same as x, so it is the same as the original x.

The increase is 26% of the original number.

Increasing a number by 5% and then by 20% is the same as increasing the original number by 26%.
