The number of key chains that must sell at $2.25 each to meet that goal is 80 keys.

  • Let the total cost of key chains be T.
  • Let the cost of each key chain be C.
  • Let the number of key chains be x.

Given the following data:

  • Total cost of key chains = $180
  • Cost of each key chain = $2.25

To write and solve the inequality:

In this exercise, we are required to translate the word problem into a mathematical (algebraic) expression and solve for the unknown variable (number):

Translating the word problem into an algebraic expression, we have;

[tex]C \times x = T[/tex]

Substituting the given parameters into the formula, we have;

[tex]2.25 \times x = 180\\\\x =\frac{180}{2.25}[/tex]

x = 80 keys
