Step-by-step explanation:
Tanner is picking three varieties of apples at an orchard: Gala, Fuji, and Jazz. Each type of apple has a different cost per pound. He knows that 1 pound of each apple variety would cost a total of $5.16, and that the cost per pound of Jazz apples is the same as the combined cost per pound of the Gala and Fuji apples. Tanner picks 12 pounds of apples, including 3 pounds of Gala and 5 pounds of Fuji, for a total cost of $21.24.
If g represents the cost per pound of Gala apples, f the cost per pound of Fuji apples, and j the cost per pound of Jazz apples, which system of equations represents this situation?
Answers
Answer:
2g + 2f = 5.16
7g + 9f = 21.24
Step-by-step explanation:
Let
Gala = g ; Fuji = f ; jazz = j
g + f + j = 5.16 - - - (1)
j = g + f - - - (2)
From (1):
g + f + g + f = 5.16
2g + 2f = 5.16 - - - (3)
Total pound picked by Tanner = 12
3 Pounds of g ; 5 pounds of f
j = 12 - (5 +3) = 4 pounds
3g + 5f + 4j = 21.24 - - - (4)
3g + 5f + 4(g + f) = 21.24
3g + 5f + 4g + 4f = 21.24
7g + 9f = 21.24 - - - - - (5)

Maria's Grocery Store buys grapefruit at a cost
of 5 for a dollar. They sell them at a price of 5
for three dollars. How many must they sell in
order to make a profit of ten dollars?
Answers
Answer: 25 grapefruits
Step-by-step explanation:
They buy grapefruit at a price of 5 per dollar. This means that the price per grapefruit is:
= 1 / 5
= $0.20 per grapefruit.
They then sell at a price of 5 per $3. The selling price per grapefruit is:
= 3 / 5
= $0.60
The profit per grapefruit is:
= 0.60 - 0.20
= $0.40
In order to make a profit of $10, they should sell:
= 10 / 0.4
= 25 grapefruits
