Complete the table and by inspection of the table find the solution to the equation 5t =35.
| t | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | .. | .. | .. | .. | .. | .. | .. | | 5t | .. | .. | .. | .. | .. | .. | .. | .. | .. | .. | .. | .. | .. | .. | .. |
| t | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | | 5t | 15 | 20 | 25 | 30 | 35 | 40 | 45 | 50 | 55 | 60 | 65 | 70 | 75 | 80 |
∵ At t = 7 ,5t = 35
∴ t = 7 is the solution.
