Set up 2 equations.(x = number of people in first class, y = tourist class)
30x + 25y = 1360
x + y = 52
You have 2 equations and 2 unknown. You can solve them.
I like to use the substitution method
Because y = 52 - x
Then 30x + 25(52 - x) = 1360, solve for x.
30x + 1300 - 25x = 1360
5x = 60
x = 12
Use the x to solve y
30(12) + 25y = 1360
360 + 25y = 1360
25y = 1000
y = 40
Substitue 2x for y in the second equation:
Rearrange to
form:
Factor:

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:
y = 5x.
Step-by-step explanation:
Every y value is the corresponding x value times 5. (For example, 3 x 5 = 15, 5 x 5 =25)
