answer: 3, you bought 3 candy bars
explanation: If your total amount spent was $16 and you need to know the how many candy bars were bought, you would subtract $7 for the magazine from the total spent of $16. Then when you come up with 9 that’s how much money they spent on candy bars. If a candy bar is $3 each, 9 divided by 3 is 3. Which means you spent $9 for 3 candy bars.
Hope this helped :) Have a wonderful day
