Solve 170*0.02+180*0.09+190*0.22+200*0.33+210*0.24+220*0.08+230*0.02

$$170 \times 0.02+180 \times 0.09+190 \times 0.22+200 \times 0.33+210 \times 0.24+220 \times 0.08+230 \times 0.02$$

Evaluate

$$200$$

Solution Steps

Multiply 170 and 0.02 to get 3.4.

$$3.4+180\times 0.09+190\times 0.22+200\times 0.33+210\times 0.24+220\times 0.08+230\times 0.02$$

Multiply 180 and 0.09 to get 16.2.

$$3.4+16.2+190\times 0.22+200\times 0.33+210\times 0.24+220\times 0.08+230\times 0.02$$

Add 3.4 and 16.2 to get 19.6.

$$19.6+190\times 0.22+200\times 0.33+210\times 0.24+220\times 0.08+230\times 0.02$$

Multiply 190 and 0.22 to get 41.8.

$$19.6+41.8+200\times 0.33+210\times 0.24+220\times 0.08+230\times 0.02$$

Add 19.6 and 41.8 to get 61.4.

$$61.4+200\times 0.33+210\times 0.24+220\times 0.08+230\times 0.02$$

Multiply 200 and 0.33 to get 66.

$$61.4+66+210\times 0.24+220\times 0.08+230\times 0.02$$

Add 61.4 and 66 to get 127.4.

$$127.4+210\times 0.24+220\times 0.08+230\times 0.02$$

Multiply 210 and 0.24 to get 50.4.

$$127.4+50.4+220\times 0.08+230\times 0.02$$

Add 127.4 and 50.4 to get 177.8.

$$177.8+220\times 0.08+230\times 0.02$$

Multiply 220 and 0.08 to get 17.6.

$$177.8+17.6+230\times 0.02$$

Add 177.8 and 17.6 to get 195.4.

$$195.4+230\times 0.02$$

Multiply 230 and 0.02 to get 4.6.

$$195.4+4.6$$

Add 195.4 and 4.6 to get 200.

$$200$$

Factor

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