1. Identify the 1st and 2nd toaster ovens based on the given condition

The condition states that the price of the $2^{\text{nd}}$ toaster oven must be equal to or lower than the $1^{\text{st}}$. Therefore, the $1^{\text{st}}$ toaster oven is the $\char36{}60$ one, and the $2^{\text{nd}}$ toaster oven is the $\char36{}40$ one.

2. Calculate the discounted price of the 1st toaster oven

Discounted price of $1^{\text{st}}$ oven $= \char36{}60 \times (100\% - 10\%) = \char36{}60 \times 0.9 = \char36{}54$

3. Calculate the discounted price of the 2nd toaster oven

Discounted price of $2^{\text{nd}}$ oven $= \char36{}40 \times (100\% - 20\%) = \char36{}40 \times 0.8 = \char36{}32$

4. Calculate the total amount paid

Total amount paid $= \char36{}54 + \char36{}32 = \char36{}86$
