There are two cell phone companies that offer different packages. Company A charges a monthly service fee of ₹34 plus ₹.05/min talk-time. Company B charges a monthly
service fee of ₹40 plus ₹.04/min talk-time.
2. Write a linear equation that models the packages offered by both companies.
(a) A = 0.05x + 34 & B = 0.04x + ₹40
(b) A = 0.04x + ₹40 & B = 0.05x + 34
(c) A = 5x + 34 & B = 4x + ₹40
(d) A = 50x + 340 & B = 4x + ₹40If the average number of minutes used each month is 1,160, which company offers the
better plan?
a. Company A = 920 & B =86.4
b. Company A = 92 & B =86.4
c. Company A = 902 & B =867
d. Company A = 920 & B =86.04
4. If the average number of minutes used each month is 420, which company offers the
better plan?
(a) Company A offers a lower monthly cost of ₹55 compared to Company B’s
monthly cost of ₹56.80.
(b) Company B offers a lower monthly cost of ₹55 compared to Company A’s
monthly cost of ₹56.80.
(c) Company A offers a lower monthly cost of ₹50 compared to Company B’s
monthly cost of ₹55.
(d) Both offer same.
5. How many minutes of talk-time would yield equal monthly statements from both
companies?
(a) 600 (b) 650 (c) 700 (d) 750
