Ask: give a teacher one, and enlarge one, is it the same one?
1. Group photo 25 yuan, send 2, that is, need to wash 33, but also give the teacher a, that is, need to wash 34
25 + 0.8 * (35-2 + 1) = 25 + 27.2 = 52.2 (yuan)
2. It costs 5.2 yuan to enlarge another one
52.2 + 5.2 = 57.4 yuan
There are 35 students in the class
57.4/35 = 1.64 yuan
