$5.80
Step-by-step explanation:
To answer, we must first subtract the toal cost Joe paid by the amount he paid for his drink, because ha paid for his drink separately. so:
3.20 - 1.75 = 1.45
And because there were a total of 4 friends, we mulitply the answer by 4:
1.45 * 4 = 5.8
So, the bag of donuts costed $5.80
