Question

1. -/1 points 0/5 submissions used in the 1990–1991 school year, the average cost for tuition, fees, and room and board at a public college was $4,064. in the 2009–2010 school year, the cost had risen to $8,040. find the percent increase in the average cost of attending a public college. (round your answer to one decimal place.) %

Explanation:

Step1: Find the increase in cost

Subtract the initial cost from the final cost. Initial cost \( C_1 = 4064 \), Final cost \( C_2 = 8040 \). Increase \( \Delta C = C_2 - C_1 = 8040 - 4064 = 3976 \).

Step2: Calculate the percent increase

Use the formula for percent increase: \( \text{Percent Increase} = \frac{\Delta C}{C_1} \times 100 \). Substitute values: \( \frac{3976}{4064} \times 100 \approx 97.8\% \).

Answer:

\( 97.8\% \)
