Answer:
21-ounce size: $3.89
Explanation:
To compare the cost, you can calculate the cost per ounce of cereal. This means you will have to divide the cost by the total number of ounces. The cereal that costs the least per ounce will be the best buy.
$4.79 / 18oz = $0.27/oz
$3.89 / 21oz = $0.19/oz
$6.49 / 32oz = $0.20/oz
The 21-ounce size is has the cheapest price per ounce, so this is your best buy.
Answer:
b. 3.3 centimeters
Step-by-step explanation:
I would say it’s the first one because if you round it it is going to be approximately 12 so that is my reason and also why it isn’t number two is because if you subtract 13.26 and 7.98 you get 5. Something so that’s why
Let c be children and a adults.
3.5c + 7a = 1771 (the total revenue is equal to the amounts made off of people)
c + a = 331 (total number of people)
The second formula becomes a = 331 - c. This can be substituted into the first formula.
3.5c + 7(331 - c) = 1771 = 7*331 - 3.5c = 1771. 7*331 = 2317, so 3.5c = 2317 - 1771 = 546.
546/3.5 = 156 = c (number of children).
c + a = 156 + a = 331 => a = 331 - 156 = 175 (number of adults).
There are 156 children and 175 adults
