Rewrite a contextual calculation efficiently

Problem

At a food drive, one box holds \(49~\text{cans}\), another holds \(51~\text{cans}\), and there are \(3\) loose cans to add. Rewrite the total number of cans in an efficient way by regrouping friendly amounts, then find the total.

(49 + 51) + 3 = 100 + 3 = 103 cans

50 + 51 + 3 = 104 cans

49 + (51 + 3) = 49 + 54 = 104 cans

(49 + 51) + 3 = 100 cans
