Question

The total cost of 8 binders is $24. The price of each binder is the same. Which equation represents the proportional relationship between the total cost, T, and the number of binders, n ?

Answer 1

Answer:
$\boxed {t=3n}$
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Solution:
What we are looking for: 
"We are looking for the equation that represents the proportional relationship between the total cost, T, and the number of binders, n." 
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
How to form the equation which represents the proportional relationship:
We would divide 24 by 8 to determine the price of each individual binder, using that we would form our equation. 
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Solve:
$24 \div 8 = 3$

$t= 3n$
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Hence, the answer would be $\boxed {t=3n}$
