$85.20/6= $14.20/pair is the answer because unit price equals cost/pairs
15x+10z is equivalent to 5(3x+2z)
I can't help u with this but I can give the formula tn=t1+(n-1)+d
The answer would be D) 98.8% because if the initial price is $25 per share, then Gavin would have spent $12,500. None of the other answers make sense since if it was just 3% or 82.3%, then it would be too much to equal $150 in return. If you were to put C, then the shares would equal $4.43 each, and If you bought 500 shares, then it would equal $2,212.5 which would be way more than $150. In the other hand, D is correct because then only 1 share would equal $0.3 and that multiplied by 500 equals precisely $150.
Hope this helps!
