In this problem, we're given information about a company that makes toys, and we're told that one toy costs 75 cents to make, and to use the space to make the toys, there is a flat rate of $4 ,500.
00:16
And they're asking us to write a linear equation describing this data.
00:22
So, our general form for linear equation is y equals mx plus b, and we need to find.
00:34
M and b.
00:38
So in this case, the part of our data that is dependent on the type of stuff or the amount of stuff that we have is this value right here.
00:52
So that value of how much it costs to make a toy is going to depend on how many toys that we make.
00:58
So it is dependent on the number of toys and therefore it is going to be our slope.
01:08
And the flat rate, that's not going to change whether we make one toy or 100 toys.
01:14
So that is going to be our b.
01:19
So if we plug these values in to our general equation, we will end up getting y equals 0 .75x plus 4 ,0005 .5 .5 .5.
01:37
And in this case, they want us to have our y be c or the cost and our x be u, or number of units.
01:48
So if we just rewrite it with the variables that they want, we get c equals .75u plus 4 ,500.
02:01
So then they ask us, how much does it cost to make 600 toys? so that is our units...
