Answer: I got p=4.15 and q=4
Step-by-step explanation: If you take 4.3 x 10^4, that would equal 43,000, which would mean that 7.5 x 10^2 equals 750. And since there are two daises that each weigh 750 milligrams, that means you would need to multiply 750*2 or add 750+750 which will give you 1,500. And when you subtract 1,500 from 43,000 that gives you 41,500. So there fore it would be 4.15 x 10^4. I don't know if this is correct but I think so.
