Step-by-step explanation:
both pumps works simultaneously to pump 160 gallons of water per hour.
With a total pond capacity of 1200 gallons, you get your answer by simply dividing the total capacity by the flow rate which gives us 7.5 hours.
note: if it is stated that the pumps where connected together on the same line (either in series or parallel) this will be a different calculation.
The mass of cocoa contained in a chocolate bar of mass 73 grams is: (73 x 54) / 100 = 39.42 grams
Okay so every part of sugar requires 4 parts of water
so
3434 cups of sugar x 4 (parts of water per 1 part of sugar) = 13736
She will need to use 13, 736 parts of water for 3, 434 parts of sugar

<h3>How to determine the balance of a bank account</h3>
Here in this question we should understand the situation like a game with the following rules for the account balance:
- A check from the account means a <em>subtraction</em> of money.
- A deposit means an <em>addition</em> of money.
- Service fee means also a <em>subtraction</em> of money.
After a careful reading, we apply the rules described above and have the following calculation:
x = $ 200 - $ 20 - $ 20 - $ 12 - $ 20 - $ 12 - $ 42 + $ 57 - $ 15
x = $ 116
