Answer:
Explanation:
Old price of Falcon's Jersey=$45.89
New price = $54.99
Therefore increase in price
 = $54.99 - $45.89 = $9.1
Therefore percentage increase in price (%) = 9.1/old price x 100
 = 9.1/45.89 x 100
 = 9.1 x 100/45.89
 = 910/45.89
 = 19.8%
Rounding off to the nearest whole number. = 20%.
