Last year, a day care center had 120 children enrolled. this year, 144 children were enrolled at the day care center. calculate the percentage of increase from last year to this year. round the answer to the nearest tenth of a percent if necessary.

a. 16.7%
b. 20%
c. 83.3%
d. 120%

Number of children that enrolled in a day care center last year = 120
Number of children that enrolled in a day care center this year = 144
Difference in the number of children = 144 - 120
                                                          = 24
Percentage of increase = (24/120) * 100
                                      = 20 percent.
From the above deduction, we can conclude that the correct option is option "B". 

17 is c. congruent means equal in size
