### Instruction:
Elias uses a bar of soap every month. If each bar of soap costs $4, how much does he spend on bars of soap in two years?

### Response:
Elias spends $4 per bar of soap * 12 bars of soap per year = $<<4*12=48>>48 per year on bars of soap.
In two years, he spends $48 per year * 2 years = $<<48*2=96>>96 on bars of soap.
