If 4 bags of chips cost $6 at this rate, 7 bags of chips will cost $10.50.
How to find rate?
Find the cost per bag:
Cost per bag = Total cost / Number of bags
Cost per bag = $6 / 4 bags
Cost per bag = $1.50
Multiply the cost per bag by the desired number of bags:
Cost of 7 bags = Cost per bag × Number of bags
Cost of 7 bags = $1.50/bag × 7 bags
Cost of 7 bags = $10.50
Therefore, 7 bags of chips will cost $10.50.
