Solve {l}{418*0.2*0.6+80*0.4}{395*0.2*0.6+77*0.4}

$$\left\{ \begin{array} { l } { 418 \times 0.2 \times 0.6 + 80 \times 0.4 } \\ { 395 \times 0.2 \times 0.6 + 77 \times 0.4 } \end{array} \right.$$

Sort

$$78.2,82.16$$

Solution Steps

Multiply 418 and 0.2 to get 83.6.

$$sort(83.6\times 0.6+80\times 0.4,395\times 0.2\times 0.6+77\times 0.4)$$

Multiply 83.6 and 0.6 to get 50.16.

$$sort(50.16+80\times 0.4,395\times 0.2\times 0.6+77\times 0.4)$$

Multiply 80 and 0.4 to get 32.

$$sort(50.16+32,395\times 0.2\times 0.6+77\times 0.4)$$

Add 50.16 and 32 to get 82.16.

$$sort(82.16,395\times 0.2\times 0.6+77\times 0.4)$$

Multiply 395 and 0.2 to get 79.

$$sort(82.16,79\times 0.6+77\times 0.4)$$

Multiply 79 and 0.6 to get 47.4.

$$sort(82.16,47.4+77\times 0.4)$$

Multiply 77 and 0.4 to get 30.8.

$$sort(82.16,47.4+30.8)$$

Add 47.4 and 30.8 to get 78.2.

$$sort(82.16,78.2)$$

To sort the list, start from a single element 82.16.

$$82.16$$

Insert 78.2 to the appropriate location in the new list.

$$78.2,82.16$$

Evaluate

$$82.16,\ 78.2$$
