Solve =30^2/6*(2*0.08+0.52+2*0.39-0.05)+

$$= \frac { 30 ^ { 2 } } { 6 } * ( 2 * 0.08 + 0.52 + 2 * 0.39 - 0.05 ) +$$

Evaluate

$$211.5$$

Solution Steps

Calculate 30 to the power of 2 and get 900.

$$\frac{900}{6}\left(2\times 0.08+0.52+2\times 0.39-0.05\right)$$

Divide 900 by 6 to get 150.

$$150\left(2\times 0.08+0.52+2\times 0.39-0.05\right)$$

Multiply 2 and 0.08 to get 0.16.

$$150\left(0.16+0.52+2\times 0.39-0.05\right)$$

Add 0.16 and 0.52 to get 0.68.

$$150\left(0.68+2\times 0.39-0.05\right)$$

Multiply 2 and 0.39 to get 0.78.

$$150\left(0.68+0.78-0.05\right)$$

Add 0.68 and 0.78 to get 1.46.

$$150\left(1.46-0.05\right)$$

Subtract 0.05 from 1.46 to get 1.41.

$$150\times 1.41$$

Multiply 150 and 1.41 to get 211.5.

$$211.5$$

Factor

$$\frac{47 \cdot 3 ^ {2}}{2} = 211\frac{1}{2} = 211.5$$
