A chocolate bar cost $1 or can be exchange for 3 wrappers . if you have $15 what is the most you would get?
15?
Do you have any wrappers?
To answer this question, we need to determine how many chocolate bars you can buy with $15 and calculate the number of wrappers obtained from those chocolate bars.
Since one chocolate bar costs $1, you can buy 15 chocolate bars with $15.
Now, let's calculate the number of wrappers you would get from these 15 chocolate bars. Each chocolate bar can be exchanged for 3 wrappers, so 15 chocolate bars will give you 15 * 3 = 45 wrappers.
With these 45 wrappers, you can exchange them for additional chocolate bars. However, keep in mind that you need 3 wrappers to exchange for 1 chocolate bar.
So, how many additional chocolate bars can you get from exchanging 45 wrappers? Divide the number of wrappers by 3 and round down to the nearest whole number. In this case, 45 wrappers divided by 3 gives us 15 additional chocolate bars.
Therefore, the total number of chocolate bars you would get with $15 is 15 (from the initial purchase) + 15 (from exchanging wrappers) = 30 chocolate bars.
