So in this problem, we're told that sales clerk has two different payment options.
00:04
So plan a says they're going to get $100 plus an additional $8 for every sale.
00:09
And plan b will give them $250 plus an additional $3 .50 per sale.
00:16
So we want to figure out how many sales per week are going to have to be made for a to yield a greater paycheck.
00:22
Well, if it's going to yield a greater paycheck, we're trying to figure out when is a greater than b.
00:27
So what we have to do is write an expression to represent each of these options.
00:32
So let's start with plan a.
00:34
Well, in plan a, they're going to get $100, no matter how many sales, plus an additional $8 per sale.
00:40
So if we call the number of sales x, that would be plus 8x.
00:44
So this will represent plan a's pagment plan.
00:48
Now for plan b, they're going to start with $250, no matter how many sales, plus the additional $3 .50 per sale, so 3 .50x.

Perfect...
