Ответ:
Since we know we can't get "2"
using a multiple of the number [10]
therefore we must check [8]
[8] * 4 = 32
72 - 32 = 40
40 / [10] = 4
[] = $ per job
With this information we could say that:
Destiny made $72 from 8 jobs, 4 being mowing, and another 4 were weeding. Mowing 4 lawns earned her $32 while weeding 4 gardens earned her $40
