Solve 2000*(0.3*1+0.4*2+0.2*3+0.1*4)

$$2000 \times (0.3 \times 1+0.4 \times 2+0.2 \times 3+0.1 \times 4)$$

Evaluate

$$4200$$

Solution Steps

Multiply 0.3 and 1 to get 0.3.

$$2000\left(0.3+0.4\times 2+0.2\times 3+0.1\times 4\right)$$

Multiply 0.4 and 2 to get 0.8.

$$2000\left(0.3+0.8+0.2\times 3+0.1\times 4\right)$$

Add 0.3 and 0.8 to get 1.1.

$$2000\left(1.1+0.2\times 3+0.1\times 4\right)$$

Multiply 0.2 and 3 to get 0.6.

$$2000\left(1.1+0.6+0.1\times 4\right)$$

Add 1.1 and 0.6 to get 1.7.

$$2000\left(1.7+0.1\times 4\right)$$

Multiply 0.1 and 4 to get 0.4.

$$2000\left(1.7+0.4\right)$$

Add 1.7 and 0.4 to get 2.1.

$$2000\times 2.1$$

Multiply 2000 and 2.1 to get 4200.

$$4200$$

Factor

$$3\times 7\times 2^{3}\times 5^{2}$$
