I= 120

Is this the problem? $$I = 4000 \times \dfrac{9 + 1}{100} \times 3$$

This is what you wrote above, so I'll help you with it. $$I = 4000 \times \dfrac{9 + 1}{100} \times 3$$ First, you must do the addition in the numerator. $$I = 4000 \times \dfrac{10}{100} \times 3$$ Now do the division in the fraction. $$I = 4000 \times 0.1 \times 3$$ Now multiply the three numbers together. $$I = 1200$$
