Solve 38.9*80+left(66-22.5right)left(65*0.7-38.9right)+22.5left(65*0.75-38.9right)

$$38.9 \cdot 80+ \left( 66-22.5 \right) \left( 65 \cdot 0.7-38.9 \right) +22.5 \left( 65 \cdot 0.75-38.9 \right)$$

Evaluate

$$3620.725$$

Solution Steps

Multiply 38.9 and 80 to get 3112.

$$3112+\left(66-22.5\right)\left(65\times 0.7-38.9\right)+22.5\left(65\times 0.75-38.9\right)$$

Subtract 22.5 from 66 to get 43.5.

$$3112+43.5\left(65\times 0.7-38.9\right)+22.5\left(65\times 0.75-38.9\right)$$

Multiply 65 and 0.7 to get 45.5.

$$3112+43.5\left(45.5-38.9\right)+22.5\left(65\times 0.75-38.9\right)$$

Subtract 38.9 from 45.5 to get 6.6.

$$3112+43.5\times 6.6+22.5\left(65\times 0.75-38.9\right)$$

Multiply 43.5 and 6.6 to get 287.1.

$$3112+287.1+22.5\left(65\times 0.75-38.9\right)$$

Add 3112 and 287.1 to get 3399.1.

$$3399.1+22.5\left(65\times 0.75-38.9\right)$$

Multiply 65 and 0.75 to get 48.75.

$$3399.1+22.5\left(48.75-38.9\right)$$

Subtract 38.9 from 48.75 to get 9.85.

$$3399.1+22.5\times 9.85$$

Multiply 22.5 and 9.85 to get 221.625.

$$3399.1+221.625$$

Add 3399.1 and 221.625 to get 3620.725.

$$3620.725$$

Factor

$$\frac{144829}{5 \cdot 2 ^ {3}} = 3620\frac{29}{40} = 3620.725$$
