1 00:00:00,867 --> 00:00:03,600 A local hospital is holding a raffle. 2 00:00:03,600 --> 00:00:07,067 The individual cost of participating in the raffle 3 00:00:07,067 --> 00:00:09,533 is given by the following expression 4 00:00:09,533 --> 00:00:15,133 5t + 3 or 5 * t + 3, where t represents 5 00:00:15,133 --> 00:00:18,533 the number of tickets one purchases. 6 00:00:18,533 --> 00:00:26,733 evaluate the expression when t = 1, t = 8 & t = 10 7 00:00:26,733 --> 00:00:33,133 Lets first take the situation when t = 1, so the 8 00:00:33,133 --> 00:00:47,133 expression becomes 5 * 1 + 3 and we know 9 00:00:47,133 --> 00:00:49,800 from order of operations, we do the multiplication 10 00:00:49,800 --> 00:00:57,333 before we do the addition. so ( 5 * 1) + 3 = 11 00:00:57,333 --> 00:01:00,800 5 + 3 = 8. 12 00:01:00,800 --> 00:01:09,400 Now we do it when t = 8, this expression becomes 13 00:01:09,400 --> 00:01:29,800 (5 * 8) + 3 = 40 + 3 = 43 14 00:01:29,800 --> 00:01:35,400 so we have the last situation when t = 10 15 00:01:35,400 --> 00:01:59,067 so we have ( 5 * 10) + 3 = 50 + 3 = 53 16 00:01:59,067 --> 99:59:59,999 and we are done
