Solve 400*25+400*35*x-14000geq1520

$$400 \times 25+400 \times 35 \times x-14000 \geq 1520$$

Solve for x

$$x\geq \frac{69}{175}$$

Solution Steps

Multiply 400 and 25 to get 10000. Multiply 400 and 35 to get 14000.

$$10000+14000x-14000\geq 1520$$

Subtract 14000 from 10000 to get -4000.

$$-4000+14000x\geq 1520$$

Add 4000 to both sides.

$$14000x\geq 1520+4000$$

Add 1520 and 4000 to get 5520.

$$14000x\geq 5520$$

Divide both sides by 14000. Since 14000 is positive, the inequality direction remains the same.

$$x\geq \frac{5520}{14000}$$

Reduce the fraction \frac{5520}{14000} to lowest terms by extracting and canceling out 80.

$$x\geq \frac{69}{175}$$
