Answer:
52
Explanation:
30% more means the original 100% plus 30% more of the original 40
That's 130% = 130/100 = 1.3
"of" means x, so it's 40 x 1.3 = 52 people
12
Change the percentage into a decimal
30% = 30/100 = 0.30
Multiply 40 with 0.30
40 x 0.30 = 12
12 more people adopted, making 52 in all.
