To find the sale price of the chair after the regular price is reduced by 25% and then by 20%, we can follow these steps:

1. Calculate the price after the first reduction of 25%:
   $$ \text{Price after 25% reduction} = 183.99 \times (1 - 0.25) $$

2. Calculate the price after the second reduction of 20%:
   $$ \text{Price after 20% reduction} = \text{Price after 25% reduction} \times (1 - 0.20) $$

Now, let's calculate the sale price of the chair after the regular price is reduced by 45%:
3. Calculate the price after the reduction of 45%:
   $$ \text{Price after 45% reduction} = 183.99 \times (1 - 0.45) $$

Let's calculate the sale prices for each scenario.
Calculate the value by following steps:
- step0: Calculate:
  $$183.99\left(1-0.25\right)$$
- step1: Subtract the numbers:
  $$183.99\times 0.75$$
- step2: Multiply the numbers:
  $$137.9925$$
Calculate or simplify the expression $$ 137.9925 * (1 - 0.20) $$.
Calculate the value by following steps:
- step0: Calculate:
  $$137.9925\left(1-0.2\right)$$
- step1: Subtract the numbers:
  $$137.9925\times 0.8$$
- step2: Multiply the numbers:
  $$110.394$$
Calculate or simplify the expression $$ 183.99 * (1 - 0.45) $$.
Calculate the value by following steps:
- step0: Calculate:
  $$183.99\left(1-0.45\right)$$
- step1: Subtract the numbers:
  $$183.99\times 0.55$$
- step2: Multiply the numbers:
  $$101.1945$$
The sale price of the chair after the regular price is reduced by 25% and then by 20% is $110.394.

The sale price of the chair after the regular price is reduced by 45% is $101.1945.
The sale price after a 25% reduction followed by a 20% reduction is \$110.39. The sale price after a 45% reduction is \$101.19.
