3 \frac{5}{12} / 2 \frac{1}{6}
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
Let A represent amount of Type A coffee pounds used.
Let B represent amount of Type B coffee pounds used
A + B = 156
B = 156 - A
A = 156 - B
5.80A + 4.65B = 826.60
580 (156 - B) + 4.65B - 826.60 = 0
904.8 - 5.80B + 4.65B - 826.60 = 0
904.8 - 1.15B - 826.60 = 0
78.2 - 1.15B = 0
78.2/1.15 = 1.15B/1.15
68 = B
B = 68 pounds of Type B coffee
There's many more steps you can take to check and etc but am too lazy to put down sorry.
