Solve (15*1.54)+(10*1.43)+(16*.79)+(4*.78)

$$(15 \times 1.54)+(10 \times 1.43)+(16 \times .79)+(4 \times .78)$$

Evaluate

$$53.16$$

Solution Steps

Multiply 15 and 1.54 to get 23.1.

$$23.1+10\times 1.43+16\times 0.79+4\times 0.78$$

Multiply 10 and 1.43 to get 14.3.

$$23.1+14.3+16\times 0.79+4\times 0.78$$

Add 23.1 and 14.3 to get 37.4.

$$37.4+16\times 0.79+4\times 0.78$$

Multiply 16 and 0.79 to get 12.64.

$$37.4+12.64+4\times 0.78$$

Add 37.4 and 12.64 to get 50.04.

$$50.04+4\times 0.78$$

Multiply 4 and 0.78 to get 3.12.

$$50.04+3.12$$

Add 50.04 and 3.12 to get 53.16.

$$53.16$$

Factor

$$\frac{3 \cdot 443}{5 ^ {2}} = 53\frac{4}{25} = 53.16$$
