Evaluate

$$19.38$$

Solution Steps

Multiply 13.5 and 0.06 to get 0.81.

$$0.81+15.5\times 0.16+17.5\times 0.18+19.5\times 0.22+21.5\times 0.2+23.5\times 0.1+25\times 0.08$$

Multiply 15.5 and 0.16 to get 2.48.

$$0.81+2.48+17.5\times 0.18+19.5\times 0.22+21.5\times 0.2+23.5\times 0.1+25\times 0.08$$

Add 0.81 and 2.48 to get 3.29.

$$3.29+17.5\times 0.18+19.5\times 0.22+21.5\times 0.2+23.5\times 0.1+25\times 0.08$$

Multiply 17.5 and 0.18 to get 3.15.

$$3.29+3.15+19.5\times 0.22+21.5\times 0.2+23.5\times 0.1+25\times 0.08$$

Add 3.29 and 3.15 to get 6.44.

$$6.44+19.5\times 0.22+21.5\times 0.2+23.5\times 0.1+25\times 0.08$$

Multiply 19.5 and 0.22 to get 4.29.

$$6.44+4.29+21.5\times 0.2+23.5\times 0.1+25\times 0.08$$

Add 6.44 and 4.29 to get 10.73.

$$10.73+21.5\times 0.2+23.5\times 0.1+25\times 0.08$$

Multiply 21.5 and 0.2 to get 4.3.

$$10.73+4.3+23.5\times 0.1+25\times 0.08$$

Add 10.73 and 4.3 to get 15.03.

$$15.03+23.5\times 0.1+25\times 0.08$$

Multiply 23.5 and 0.1 to get 2.35.

$$15.03+2.35+25\times 0.08$$

Add 15.03 and 2.35 to get 17.38.

$$17.38+25\times 0.08$$

Multiply 25 and 0.08 to get 2.

$$17.38+2$$

Add 17.38 and 2 to get 19.38.

$$19.38$$

Factor

$$\frac{3 \cdot 17 \cdot 19}{2 \cdot 5 ^ {2}} = 19\frac{19}{50} = 19.38$$
