Remind your students that there is more than one way to begin solving a division problem. Tell your students to "just begin" and then to adjust as needed. Give your students these problems: 531 ÷ 16; 364 ÷ 22; 1,506 ÷ 24; 3,186 ÷ 45. Ask them to first estimate the quotientsand then to find the actual quotients.

Answer:
It takes 13 months for the second phone to be less expensive than the first phone.
Step-by-step explanation:
First phone: y = 100 + 55x
Second phone: y = 150 + 51x
(x = number of months, y = total cost)
Make a T-Chart.
First phone: Second phone:
<u> x | y </u> <u> x | y </u>
0 | 100 0 | 150
1 | 155 1 | 201
2 | 210 2 | 252
3 | 265 3 | 303
4 | 320 4 | 354
5 | 375 5 | 405
6 | 430 6 | 456
7 | 485 7 | 507
9 | 595 9 | 609
10 | 650 10 | 660
11 | 705 11 | 711
12 | 760 12 | 762
13 | 815 13 | 813
After 13 months, the second phone will have costed $2 less than the first phone, and the price of the second will continue to be lower than the first.
The correct answer is 4x10 to the 4th power
