This problem tells us that the manager of Cups R’ us handed out a certain amount of coupons to his costumers, so we can write this as follows:
ON MONDAY:
He handed out 125 coupons
ON TUESDAY:
He handed out c coupons
ON WEDNESDAY:
He handed out 220 coupons
Therefore, we can write an expression for the total number of coupons the manager handed out as the sum of the number of coupons he handed out each day, that is:

Answer:
$ 0.8.
Step-by-step explanation:
1) if to assume, 'c' - price of the coffee and 'd' - price of the doughnuts, then
2) it is possible to write the equation 1 (when five MinB enter): 3d+5c=3.3;
3) it is possible to write the equation 2 (when three aliens entered): 4d+3c=2.75;
5) if c=0.45 and d=0.35, then Ag.Z. paid 0.35+0.45=$ 0.8.
