9. Draw a model with 3x4 model and shade in 9 squares; say its 75%
Answer: Choice C) $15
There are two ways to get this answer
Method 1 is to subtract 700-550 = 150 and then take 10% of that to get 15
We take 10% since this is the percentage Ricardo has to pay (the employer takes care of the other 90%)
Method 2 is to take 10% of 700 and 550 to get 70 and 55 respectively. Then subtract to get 70-55 = 15
Either way the answer is 15
