Answer:
The percent increase in the number of bicycles sold from last year to this year is 13.64%
Explanation:
To do this we have to divide the number of bicycles sold this year by the number of bicycles sold last year
625 / 550 = 25/22
To know how much it is in percentage we have to multiply it by 100
25/22 * 100 = 113.64%
To know the percentage increase we simply have to subtract 100%
113.64% - 100% = 13.64%
the percent increase in the number of bicycles sold from last year to this year is 13.64%
