Short answer

Question: Express the following quantities as integers: a. Dow-Jones Index loss of 120 points b. Scuba Diver's depth of 145 feet c. Deposit of $50 into a checking account d. Oakland Raiders' 15-yard penalty loss e. Withdrawal of $75 from a checking account Answer: a. -120 b. -145 c. 50 d. -15 e. -75

Step-by-step solution

a. Dow-Jones Index Loss of 120 points#

Since the Dow-Jones stock index lost 120 points, it is a negative situation; thus, the integer representation would be -120.

b. Scuba Diver's Depth of 145 feet#

The scuba diver is below the surface, which is a negative depth. So, we can represent the depth as an integer by writing -145.

c. Deposit of $50 into checking account#

A deposit implies a gain or increase in money. Therefore, the integer representation for this positive value would be simply +50, or simply 50.

d. Oakland Raiders' 15-yard Penalty Loss#

Losing yards due to a penalty is a negative situation in the game. To express this as an integer, we will write it as -15, which represents the loss of 15 yards.

e. Withdrawal of $75 from Checking Account#

When withdrawing money, there is a decrease in the balance, which is considered a negative situation. The integer representation for the withdrawal of $75 would be -75.
