Answer 1

The correct model to solve this problem is subtraction.

Algorithm: Current Depth = Initial Depth - Distance Dived

Let's apply this algorithm to the problem:

Initial Depth: 1,200 feet
Distance Dived: 943 feet

Current Depth = 1,200 - 943
Current Depth = 257 feet

Therefore, the submarine's current depth is 257 feet.

Answer 2

What model matches the situation: Maxwell’s bank account is currently in the negative by $47. He spent another $29 at the store. What is his current balance?(1 point)

Answer 3

The correct model to solve this problem is addition.

Algorithm: Current Balance = Initial Balance + Money Spent (if in the negative, it is considered as spent)

Let's apply this algorithm to the problem:

Initial Balance: -47 dollars
Money Spent: 29 dollars

Current Balance = -47 + 29
Current Balance = -18 dollars

Therefore, Maxwell's current balance is -18 dollars, meaning he still owes $18.
