Answer:
15%
Explanation:
IF 100 percent is 180 dollars then dividing 180 by 100 will tell us what is 1 percent of 180
which is 1.8
Now knowing this we find the difference from 189 to 207 which is 207 minus 189
=27 dollars increase
FROM thier we divide 1.8 by 27 to see how much 27 dollars is of 180, thefore finding the percent increase of the table.
27/1.8 = 15
----
SO there was a 15 percent increase
