At the autumn market, pumpkin bread is priced at $3 a loaf, and apple cider is $2 a bottle. A customer spent exactly $19 and bought a total of 8 items (a mix of pumpkin bread loaves and cider bottles). How many loaves of pumpkin bread did they buy?
3 loaves
Let P be pumpkin bread ($3) and C be cider ($2). P + C = 8 items, so C = 8 - P. Cost equation: 3P + 2(8 - P) = 19. 3P + 16 - 2P = 19. P + 16 = 19, so P = 3. They bought 3 loaves of pumpkin bread and 5 bottles of cider.
