Solve -1(0.02)+1(0.01)+3(0.9)+10(0.07)

$$-1(0.02)+1(0.01)+3(0.9)+10(0.07)$$

Evaluate

$$3.39$$

Solution Steps

Multiply -1 and 0.02 to get -0.02.

$$-0.02+1\times 0.01+3\times 0.9+10\times 0.07$$

Multiply 1 and 0.01 to get 0.01.

$$-0.02+0.01+3\times 0.9+10\times 0.07$$

Add -0.02 and 0.01 to get -0.01.

$$-0.01+3\times 0.9+10\times 0.07$$

Multiply 3 and 0.9 to get 2.7.

$$-0.01+2.7+10\times 0.07$$

Add -0.01 and 2.7 to get 2.69.

$$2.69+10\times 0.07$$

Multiply 10 and 0.07 to get 0.7.

$$2.69+0.7$$

Add 2.69 and 0.7 to get 3.39.

$$3.39$$

Factor

$$\frac{3 \cdot 113}{2 ^ {2} \cdot 5 ^ {2}} = 3\frac{39}{100} = 3.39$$
