Solve 0.5*2.57*(15.3*60+1.6*120)+0.53*450

$$0.5 \times 2.57 \times (15.3 \times 60+1.6 \times 120)+0.53 \times 450$$

Evaluate

$$1664.85$$

Solution Steps

Multiply 0.5 and 2.57 to get 1.285.

$$1.285\left(15.3\times 60+1.6\times 120\right)+0.53\times 450$$

Multiply 15.3 and 60 to get 918.

$$1.285\left(918+1.6\times 120\right)+0.53\times 450$$

Multiply 1.6 and 120 to get 192.

$$1.285\left(918+192\right)+0.53\times 450$$

Add 918 and 192 to get 1110.

$$1.285\times 1110+0.53\times 450$$

Multiply 1.285 and 1110 to get 1426.35.

$$1426.35+0.53\times 450$$

Multiply 0.53 and 450 to get 238.5.

$$1426.35+238.5$$

Add 1426.35 and 238.5 to get 1664.85.

$$1664.85$$

Factor

$$\frac{3 \cdot 11 \cdot 1009}{5 \cdot 2 ^ {2}} = 1664\frac{17}{20} = 1664.85$$
