This is a system of equations problem.
Blueberry = X, blackberry = Y
Joe:
5x + 10y = 135
James:
x + 9y = 104
Let’s isolate x from James’ equation.
x = 104 - 9y
Now substitute that into the first equation.
5(104 - 9y) + 10y = 135
520 - 45y + 10y = 135
-35y = -385
y = -385/-35. The negatives cancel out, leaving us with $11 for blackberries.
Now we can substitute that value into James’s equation.
x + 9(11) = 104
x = 104 - 99
x = $5
Final answer: Blueberry pies cost $5, blackberry pies cost $11.
The most cookies Heidy can make is 36 cookies.
<h3>How to calculate how many cookies can Heidy make?</h3>
To know how many cookies Heidy can make, you have to take into account the following information:
12 cookies need the following ingredients:
- 125g butter
- 200g flour
- 50g sugar
In the case in which Heidy has more ingredients, we must carry out the following operations:
Divide the quantities, in the reference quantity we have:
- 500g of butter ÷ 125g of butter = 4
- 700g flour ÷ 200g flour = 3.5
- 250g of sugar ÷ 50g of sugar = 5
According to the above, we must take into account the lowest value of all because if that ingredient is enough, we can infer that the rest of the ingredients also.
So the number of cookies Heidy can make are:
12 × 3.5 = 42

Answer:
There's no picture.
Step-by-step explanation:
There ya go, the graphing
6 chewy toys and 6 cat collars are needed to have the same amount or price at both stores.
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more angles and variables.
Let x represent the number of dogs and y represent the number of cats collars. Hence:
At Marco's market:
2x + 6y = 48 (1)
At Sonia's superstore:
4x + 4y = 48 (2)
Graphing both equations, the solution is at (6,6)
6 chewy toys and 6 cat collars are needed to have the same amount or price at both stores.
