Kayla buys two pairs of jeans for j dollars each and one shirt for 15 dollars. The cost of one pair of jeans is $22.5  (twenty-two dollars and fifty cents)

From the given information

  • Let the cost of two pairs of jeans be 2j
  • The cost of 1 shirt = 15
  • Total amount to spent = $60

∴

The equation is said to be expressed as:

  • 2j + 15 - 60 = 0

Collect like terms

  • 2j = 60 - 15
  • 2j = 45

Divide both sides by 2

  • [tex]\mathbf{\dfrac{2j}{2}= \dfrac{45}{2}}[/tex]
  • j = 22.5

Therefore, we can conclude that the cost of one pair of jeans is  $22.5  (twenty-two dollars and fifty cents).
