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.
