Portobello mushrooms sell for $6.60/kg and oyster mushrooms sell for $11.00/kg. Find the mass of each type of mushroom in 1-kg bags selling for $8.36.
Answer provided by our tutors
x = kg of portobello mushrooms sold
y = kg of oyster mushrooms sold
x + y = 1
6.60x + 11.00y = 8.36
x = 0.6 kg or 600 gr
y = 0.4 kg or 400 gr
600 grams of portobello mushrooms and 400 grams of oyster mushrooms were sold for $8.36 in a 1-kg bag.
