If James buys pistachios for $10 per can and each can is 5 ounces, then he spends $10/5 ounces = $2 per ounce of pistachios.
If he eats 30 ounces of pistachios every 5 days, then he eats 30/5 = 6 ounces of pistachios per day.
If there are 7 days in a week, then he eats 6 ounces x 7 days = 42 ounces of pistachios per week.
If he spends $2 per ounce of pistachios and eats 42 ounces per week, then he spends $2 x 42 ounces = $84 per week on pistachios.
#### 84
The answer is: 84
