Solve 9*0.25+13*0.75+17*0.1+21*0.05

$$9 \cdot 0.25+13 \cdot 0.75+17 \cdot 0.1+21 \cdot 0.05$$

Evaluate

$$14.75$$

Solution Steps

Multiply 9 and 0.25 to get 2.25.

$$2.25+13\times 0.75+17\times 0.1+21\times 0.05$$

Multiply 13 and 0.75 to get 9.75.

$$2.25+9.75+17\times 0.1+21\times 0.05$$

Add 2.25 and 9.75 to get 12.

$$12+17\times 0.1+21\times 0.05$$

Multiply 17 and 0.1 to get 1.7.

$$12+1.7+21\times 0.05$$

Add 12 and 1.7 to get 13.7.

$$13.7+21\times 0.05$$

Multiply 21 and 0.05 to get 1.05.

$$13.7+1.05$$

Add 13.7 and 1.05 to get 14.75.

$$14.75$$

Factor

$$\frac{59}{2 ^ {2}} = 14\frac{3}{4} = 14.75$$
