the question in English
Juan has blue cubes with a 55 mm edge and red cubes with a 45 mm edge. He stacks them in two columns, one of each color; he wants the two columns to be the same height. How many cubes does he need, as a minimum, of each color?
Let
x---------> the number of blue cubes
y--------> the number of red cubes
we know that
Juan wants that the two columns to be the same height
so

solve for y

I proceed to calculate a table, assuming values of x to calculate the value of y. When the values of x and y are whole numbers, I will have found the solution.
the table in the attached figure
therefore
<u>the answer is</u>
9 blue cubes
11 red cubes
I believe it’s the last option sorry if I’m incorrect
Answer:
300a + 450b ≤ 6000
Step-by-step explanation:
Given:
Cost of electric mower = $300
Cost of gas mower = $450
Total number of mower = 25
Cost of total mower is at least = $6,000
Find:
Number of each mower equation
Computation:
Number of electric mower = a
Number of gas mower = b
So,
Equations
a + b ≤ 25 ........ Equation 1
300a + 450b ≤ 6000 ....... Equation 1
