Answer:
Hanna
Step-by-step explanation:
When you find out the % of a number you turn the percentage into a decimal.
150%=1.5
Then you multiply by your original number.
70 x 1.5 = 105
Finally you add that to your original number.
105 + 70 = 175
Since Hanna said increasing 70 by 150% is 175, she is correct.
