Final answer:
To find out how many containers Angie could buy, divide the total amount spent ($6.40) by the cost per container ($0.80). Angie bought 8 containers of yogurt for $6.40, making option (b) the correct choice.
Step-by-step explanation:
The question involves calculating the number of yogurt containers Angie could buy with $6.40 when each container costs $0.80. To find the answer, we divide the total amount spent by the cost per container. This calculation is:
Total containers = Total spent ($6.40) / Cost per container ($0.80)
Performing the division, we find:
Total containers = $6.40 / $0.80 = 8 containers
Therefore, Angie bought 8 containers of yogurt for $6.40. Out of the options given, option (b) 8 containers is the correct answer.
