To find the unit price for the yogurt and applesauce, we first need to calculate the price per container for each item.
For yogurt:
- Price for 6 containers of yogurt = $4.29
- Unit price = Total price / Number of containers = $4.29 / 6 = $0.715 per container
For applesauce:
- Price for 8 containers of applesauce = $3.39
- Unit price = Total price / Number of containers = $3.39 / 8 = $0.42375 per container
Now, we calculate the cost for 5 containers of yogurt and 3 containers of applesauce.
Cost of 5 containers of yogurt:
- Cost = Number of containers × Unit price = 5 × $0.715 = $3.575
Cost of 3 containers of applesauce:
- Cost = Number of containers × Unit price = 3 × $0.42375 = $1.27125
Now, we add the costs together to find the total cost.
Total cost = Cost of yogurt + Cost of applesauce
Total cost = $3.575 + $1.27125 = $4.84625
Rounding it to two decimal places, we get $4.85.
So the answer is b. $4.85.
