I was preparing a dinner party and bought a bunch of chicken and potatoes. Chicken cost $6.50 per pound and potatoes were $1 per pound. On my first trip to the store, I spent $24.50. When I realized that I didn’t have enough food – everyone was bringing a date, so I’d need to shop again(!), I went back to the store for more, but the prices had change. On my second trip to the store, the chicken was up to $7 per pound and the potatoes were at $1.25 per pound. The total bill for the same amount of food was now $27.25. How many pounds of chicken did I get each time I went to the store? How many pounds of potatoes did my recipe call for?
