710Total number of muffins sold on Sunday
= 10 u + 53 + 3 u
= 13 u + 53
13 u + 53 = 677
13 u = 677 - 53
13 u = 624
1 u = 624 ÷ 13 = 48
Total number of muffins sold on Saturday
= 10 u + 53 + 10 u
= 20 u + 53
Total number of muffins sold on both days
= 13 u + 53 + 20 u + 53
= 33 u + 106
= 33 x 48 + 106
= 1584 + 106
= 1690
Total amount received from the sale of muffins on both days
= 1690 x 5.90
= $9971
Answer(s): $9971
