Final answer:
The unit rate price for one hot chocolate bomb, when six are bought for $42, is $7 per bomb.
Step-by-step explanation:
The student is asking about the unit rate price for one item when six hot chocolate bombs were purchased for $42. To find the unit price, you divide the total amount spent by the quantity of items. So, we divide $42 by 6 to get the unit price per hot chocolate bomb.
$42 ÷ 6 = $7
Therefore, the unit rate price for one hot chocolate bomb is $7.
