Amanda is decorating her home and wants to buy some house plants. She is interested in three types of plants costing $7, $10, and $13. If she has budgeted $150 for the plants and whats to buy exactly 15 of them, what are her options? 
let x=number of $7 plants
let y=number of $10 plants
let z=number of $13 plants
..

 
by trial and error:
x=5, y=5, z=5
x+y+z=15
5*7+5*10*5*13=35+50+65=$150
one of her options: buy 5 of each type of plant
