Explanation: “Fancy lunch for $5 each” the key word: each, tells us that one lunch cost $5 Since he is buying 12 lunches you would need to multiple 5 by 12 to get 60 dollars.
The $25 is the amount of money to join the lunch club, so that mean you would need to add that to get the total money he spend.
Equation would be C=5(12)+25 12= lunches he bought
