Answer:
42.5 if rounding 43 for B
Step-by-step explanation:
P is the variable so put 100 under it
Then on the first empty fraction put 17/40
Cross multiply
You will get 40p=17x100
So then you multiply 17 by 100
1700
divided both sides by 40
Get the variable alone
Divide 1700 by 40
get 42.5
If your teacher is as annoying as mine round to 43
79 would be the right answers
