Juan buys peaches and grapefruit at the store.  He writes the equations shown to model the relationship between the number of pounds of peaches, p, and the number of pounds of grapefruit, g, that he buys.

​p + g = 2.5
1.58p + 1.09g = 3.46

What is the total number of pounds of peaches and grapefruit that Juan buys?
