Question

The equation C = 20n + 35 represents the relationship between the cost of school volleyball uniforms,

Answer 1

Answer:

Given the equation

• C = 20n + 35

We need:

• n ≥ 15 and C ≤ 600

following

• 20n + 35 ≤ 600
• 20n ≤ 565
• n ≤ 565/20
• n ≤ 28 (rounded to the whole number)

Considering that n ≥ 15, we have:

• 15 ≤ n ≤ 28

And the cost is going to be:

• 20*15 + 35 ≤ C ≤ 20*28 + 35
• 335 ≤ C ≤ 595
