TeaPots n Treasures sells loose Oolong tea for $2.15 per ounce. Donna mixed Oolong tea with shaved almonds that sell for $0.95 per ounce to create the Market Street Oolong blend that sells for $1.85 per ounce. One week, she made 300 oz of Market Street Oolong. How much tea and how much shaved almonds did Donna use?

If there were x oz of almonds, then the rest (300-x) was tea.

0.95x + 2.15(300-x) = 1.85(300)

To find out how much tea and shaved almonds Donna used to make the Market Street Oolong blend, we can set up a system of equations based on the given information.

Let's assume that Donna used x ounces of loose Oolong tea and y ounces of shaved almonds.

From the given information, we know the following:

1) The price of loose Oolong tea is $2.15 per ounce.
2) The price of shaved almonds is $0.95 per ounce.
3) The price of the Market Street Oolong blend is $1.85 per ounce.
4) Donna made a total of 300 ounces of the Market Street Oolong blend.

Now, let's set up the equations:

Equation 1: The total cost of the loose Oolong tea used is equal to the cost per ounce multiplied by the number of ounces used:
2.15x = ...

Equation 2: The total cost of the shaved almonds used is equal to the cost per ounce multiplied by the number of ounces used:
0.95y = ...

Equation 3: The total cost of the Market Street Oolong blend is equal to the cost per ounce multiplied by the number of ounces produced:
1.85 * 300 = ...

To find the values of x and y, we need to solve this system of equations:

2.15x + 0.95y = 1.85 * 300

Now, let's solve for x and y:

Step 1: Multiply both sides of Equation 3 by 300:
555 = 2.15x + 0.95y

Step 2: Rearrange Equation 2 to solve for y:
0.95y = 555 - 2.15x
y = (555 - 2.15x) / 0.95

Step 3: Substitute the expression for y from Step 2 into Equation 1:
2.15x + 0.95((555 - 2.15x) / 0.95) = 1.85 * 300

Simplifying the equation, we can solve for x.

Once we find the value of x, we can substitute it back into Equation 2 to find y.

By solving these equations and substituting in the values, we can determine the amount of tea and shaved almonds Donna used to make the Market Street Oolong blend.
