what is the percent of increase from 4000 to 7000?
write your answer using a percent sign (%).

Explanation:

Step1: Find the increase amount

The increase is the new value minus the original value. So, $7000 - 4000 = 3000$.

Step2: Calculate the percent increase

The formula for percent increase is $\frac{\text{Increase}}{\text{Original Value}} \times 100\%$. Substituting the values, we get $\frac{3000}{4000} \times 100\%$.
Simplify $\frac{3000}{4000} = 0.75$, then $0.75 \times 100\% = 75\%$.

Answer:

75%
