Answer: option D is the correct answer.
Step-by-step explanation:
Let m represent the total number of minutes that the phone is used in a month.
Let C represent the amount of the bill for using m minutes.
His monthly bill will be $32.99 each month which includes 100 minutes of use. Additional minutes will cost $0.19 per minute. It means that the cost of additional minutes is
0.19(m - 100). Therefore, the linear model representing the amount of the bill would be
C = 0.19(m - 100) + 32.99

Answer:
a. 311 hours
b. i. $3,100 in receipts
ii. $2,799 in expenses.
Step-by-step explanation:
a. The company is making $10 per hour and spending $9 an hour. Their profit is therefore:
= 10 - 9
= $1 per hour
Since they spent $311 on the new equipment, the amount of time it would take for them to make this back is:
= 311 / 1
= 311 hours
b. In 311 hours, the total receipts would be:
= 311 * 10
= $3,110
The expenses would be:
= 311 * 9
= $2,799
