This problem says you offer to go to the local deli and pick up sandwiches for lunch.
00:05
You have 30 total dollars to spend.
00:07
Chicken sandwiches cost $3 each and tuna sandwiches cost $1 .50 each.
00:11
How many sandwiches can you purchase for $30? so the expression that represents our scenario is that we are going to spend $3 for every chicken sandwich we get and a $1 .50 or $1 .5 times every tuna sandwich we get.
00:25
And that's going to equal the total that we're going to pay.
00:28
So we want our total to be equal to 30 or less than 30.
00:32
But if it's more than 30, then that's not our option.
00:34
So first for a and b, we kind of already have a problem before we even look at the tuna sandwiches, because if we have 11 chicken sandwiches, 11 times our three that our chicken sandwiches are worth would be $33.
00:47
And that's already more than we have of $30.
00:49
So a can't be the right choice.
00:51
For 12 times c, we're going to have the same problem.
00:53
12 times 3 is going to give us 36...
