Answer: $49
Explanation: To find out how much money Lionel raised, we need to calculate the total number of bars he sold and then multiply it by the price per bar.
On Saturday, Lionel sold 16 bars, and on Sunday, he sold 12 bars. So, the total number of bars sold is 16 + 12 = 28.
Since each bar sold for $1.75, we can multiply the total number of bars (28) by the price per bar ($1.75) to find the total amount of money raised.
28 bars * $1.75/bar = $49
Therefore, Lionel raised $49.
