Solve 18000a-18000/1000*8*25-18000/1000*100

$$18000 a - \frac { 18000 } { 1000 } \times 8 \times 25 - \frac { 18000 } { 1000 } \times 100$$

Evaluate

$$18000a-5400$$

Solution Steps

Divide 18000 by 1000 to get 18.

$$18000a-18\times 8\times 25-\frac{18000}{1000}\times 100$$

Multiply 18 and 8 to get 144.

$$18000a-144\times 25-\frac{18000}{1000}\times 100$$

Multiply 144 and 25 to get 3600.

$$18000a-3600-\frac{18000}{1000}\times 100$$

Divide 18000 by 1000 to get 18.

$$18000a-3600-18\times 100$$

Multiply 18 and 100 to get 1800.

$$18000a-3600-1800$$

Subtract 1800 from -3600 to get -5400.

$$18000a-5400$$

Factor

$$1800\left(10a-3\right)$$

Solution Steps

Factor out 1800.

$$1800\left(10a-3\right)$$

Consider 10a-2-1. Multiply and combine like terms.

$$10a-3$$

Rewrite the complete factored expression.

$$1800\left(10a-3\right)$$
