Hello Lily might be a bit late but in case you ever decide to pop back here to check.
For 2a, since we you correctly identified the numbers and got the answer, I won't be explaining too in-depth.
For 2b, firstly we find the total amount of cupcakes sold by D (22 + 34 = 56). From there, because the question mentioned that D sold 80% of their total cupcakes, we can assume that 80% = 56. To find the total amount we just find 100% (56/80 x 100 = 70).
For 2c, because we identified that D has 7 units, we can assume that 7 units = 70. Hence, to find E which is 6 units, we simply find 1 unit before multiplying by 6 (70/7 x 6 = 60). As the question asks for possible sets of value, any 2 numbers are fine so long they add up to 60 (For example, 35 and 25, 43 and 17 etc).
Good luck for your studies! :)
