Solve 50a+(40-a)*40≥1800

Evaluate

50 a + (40 - a) \times 40 \geq 1800

Multiply the terms

50 a + 40 (40 - a) \geq 1800

Move the expression to the left side

50 a + 40 (40 - a) - 1800 \geq 0

Calculate the sum or difference

More Steps

10 a - 200 \geq 0

Move the constant to the right side

10 a \geq 0 + 200

Removing 0 doesn't change the value,so remove it from the expression

10 a \geq 200

Divide both sides

\frac{10 a}{10} \geq \frac{200}{10}

Divide the numbers

a \geq \frac{200}{10}

Solution

More Steps

a \geq 20
