55,000,000 is the answer :D
In the y=mx+b format or a linear equation, this would be y=15x+25
If he sold 25 boxes in all and he sold 7 today then he would of sold 25 - 7 boxes yesterday. Josh sold 18 boxes yesterday.
Today = 7
Yesterday = 18
Total = 25
7 + x = 25, when x = Yesterdays sold boxes.
Hope this helps :)
