I know how to figure out the answer though I am at school right now, I will be home in about 20 minutes. I will answer first thing when I get back.
Answer:
The easiest way of calculating discount is, in this case, to multiply the normal price $3200 by 12 then divide it by one hundred. So, the discount is equal to $384. To calculate the sales price, simply deduct the discount of $384 from the original price $3200 then get $2816 as the sales price.
Can you make the answer clearer. I would be glad to help you. I just don't understand where it says "the sum of three numbers is 16 the sum of twice the first number"
