Data:
• Jenn wants to spend ,at most $85.
,
• She has to buy ,a cake, that, costs $25.
,
• Each ,entrée is ,$17,.
Procedure:
0. The notation ,a ≤ b, means that ,a, is ,less than or equal, to ,b, (equivalently, ,“at most”, ,b,).
,
1. Jenn has to buy ,one ,cake, so it is a fixed cost (a constant).
,
2. Jenn has to buy entrée, but the problem does not say how many, just that what she spends at most $85. Therefore, the entreé is a ,variable ,cost.
