To avoid mistakes, Liam writes a careful cost–benefit table. Liam has $12 saved and earns about $4 per week. The skateboard costs $45 and Liam wants it in 7 weeks. Today, Liam can choose a bigger treat or a smaller treat. Cost–Benefit Table: Choice | Total in 7 weeks | Costs | Benefits --- | --- | --- | --- Buy craft supplies ($13) | $27 | Spend $13; less saved for goal | Big fun right away Buy popcorn and soda ($7) | $33 | Spend $7; save a little less | Small fun right away Buy nothing (save all) | $40 | Give up both treats today | Most money toward the goal Which conclusion correctly uses the cost–benefit table?
