Final answer:
To find the number of pounds of each kind of fruit Theresa can buy, we'll set up a system of equations. Let x be the pounds of oranges and y be the pounds of pineapples. The equation in standard form is 2.50x + 4.00y = 50.
Step-by-step explanation:
To find the number of pounds of each kind of fruit Theresa can buy, we'll set up a system of equations.
Let's assume she can buy x pounds of oranges and y pounds of pineapples.
The cost of the oranges will be 2.50x dollars and the cost of the pineapples will be 4.00y dollars.
Since Theresa has $50 to spend, we can create the equation: 2.50x + 4.00y = 50.
This is the equation in standard form that represents how many pounds of each kind of fruit Theresa can buy.
