To promote the launch of a new Cadbury's chocolate bar, they are offering a ''buy four, get one free,'' deal. If each chocolate bar costs thirty cents, how much would ten chocolate bars cost?

So the promo is buy 4 get 1 free. So, when you buy 8, you'll get 2 free.

Math: 8 * .30 = $2.40
Answer: $2.40 is how much 10 bars would cost! Hope it helped :)

Thanks! Makes sense now.

Yep, No Problem! Happy to help!

To calculate the cost of ten chocolate bars with the "buy four, get one free" deal, we need to determine how many chocolate bars we actually need to pay for. Since for every four chocolate bars, we get one free, we can divide the total number of chocolate bars by 4 to find out how many we need to pay for.

In this case, we have ten chocolate bars. We divide 10 by 4 to get 2 remainder 2. This means that we will have 2 groups of four chocolate bars that we need to pay for, and 2 additional individual chocolate bars left over.

So, for the first 8 chocolate bars (2 groups of 4), we need to pay for all of them. Thus, the cost for the first 8 chocolate bars is 8 * $0.30 = $2.40.

Now, we have 2 chocolate bars left. Since the deal is "buy four, get one free," and we don't have 4 bars left to qualify for the free one, we need to pay for these two individually. Thus, the cost for the remaining 2 chocolate bars is 2 * $0.30 = $0.60.

Adding the cost of the two sets together, the total cost for ten chocolate bars would be $2.40 + $0.60 = $3.00.
