  1. Find Cost Difference: Find the difference in cost between 19901990 and 20102010. $60.00$17.00=$43.00\$60.00 - \$17.00 = \$43.00.
  2. Calculate Percent Increase: Calculate the percent increase using the formula (Difference/Original Price)×100%(\text{Difference}/\text{Original Price}) \times 100\%. So, ($43.00/$17.00)×100%=252.94%(\$43.00/\$17.00) \times 100\% = 252.94\%.
