Philip, Dylan, and Corey have sold a total of 290 school buttons. Corey sold 64 more school buttons than Philip. Dylan sold 62 fewer school buttons than Philip. How many school buttons did Dylan sell?

1 answer

Notice that all data is in reference to Philip, so
let number of buttons for Philip be x
number for Corey ---- x+64
Dylan ---- x - 62

x + x+64 + x-62 = 290

now just solve for x , then sub into my definitions.
