A local hospital is holding[br]a raffle as a fundraiser.

0:00:03.820,0:00:06.390
The individual cost of[br]participating in the raffle

0:00:06.390,0:00:10.810
is given by the following[br]expression-- 5t plus 3,

0:00:10.810,0:00:14.610
or 5 times t plus 3,[br]where t represents

0:00:14.610,0:00:17.320
the number of tickets[br]someone purchases.

0:00:17.320,0:00:22.330
Evaluate the expression when t[br]is equal to 1, t is equal to 8,

0:00:22.330,0:00:25.790
and t is equal to 10.

0:00:25.790,0:00:27.620
So let's first[br]take the situation

0:00:27.620,0:00:31.530
where t is equal to 1.

0:00:31.530,0:00:33.360
Then this expression[br]right over here

0:00:33.360,0:00:39.750
becomes-- and I'll use that[br]same color-- becomes 5 times 1.

0:00:39.750,0:00:43.680
5 times 1 plus 3.

0:00:43.680,0:00:47.850
5 times 1 plus 3, and we know[br]from order of operations,

0:00:47.850,0:00:50.640
you do the multiplication[br]before you do the addition.

0:00:50.640,0:00:54.870
So this will be 5[br]times 1 is 5 plus 3,

0:00:54.870,0:00:59.300
and then this is[br]clearly equal to 8.

0:00:59.300,0:01:02.360
Now let's do it when[br]t is equal to 8.

0:01:02.360,0:01:07.300
So when t is equal to 8,[br]this expression becomes--

0:01:07.300,0:01:16.990
and I'll do the same colors[br]again-- 5 times 8 plus 3.

0:01:16.990,0:01:19.690
Same color of green.

0:01:19.690,0:01:25.650
And once again, 5 times 8 is[br]40, and then we have the plus 3,

0:01:25.650,0:01:28.730
there so this is equal to 43.

0:01:28.730,0:01:30.270
And so we have the[br]last situation,

0:01:30.270,0:01:31.900
with t is equal to 10.

0:01:31.900,0:01:34.440
I'll do that in blue.

0:01:34.440,0:01:36.660
So we have 5 times 10.

0:01:36.660,0:01:41.670
So 5t is 5 times 10.

0:01:41.670,0:01:43.330
Instead of a t, put a 10 there.

0:01:43.330,0:01:47.249
5 times 10 plus 3.

0:01:47.249,0:01:49.040
That's a slightly[br]different shade of green,

0:01:49.040,0:01:50.248
but I think you get the idea.

0:01:50.248,0:01:52.970
5 times 10 is 50.

0:01:52.970,0:01:55.310
We do 50, and then we're going[br]to have to add 3 to that,

0:01:55.310,0:01:58.400
and that is equal to 53.

0:01:58.400,0:02:00.190
And we're done.
