nah its ok. Thanks though!

Answer 8

Later she posted it was supposed to be 70% of 210 not 70% or 210. So we gave her the wrong answer. Should have been 147 not 300.

Answer 9

increased by 70% OR 210, which i took to mean that 210 was 70% of some number, and that number would be 300

Answer 10

"of" , "or" one letter makes all the difference!
