9. On a spelling test Carlos had to spell 25 words. He earned 4 points for every word he spelled correctly. Which equation can be used to find p, the total number of points Carlos earnedfor spelling w words correctly? A p w −. B p = 4. ) C p w. = 4. D p = +. 4.
I know the answer but what is the best way to make my son understand this problem.

p = 4w
just take the number of words and multiply by the score for each word. 
It looks as though none of the choices is correct.
What do you think is the answer?

ans is c p=4w.
@ steve I told him the same way but he said there no multiplication sign. 
Steve's answer is correct.
p = 4w
