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

- Total amount to spent = $60
∴
The equation is said to be expressed as:
- 2j + 15 - 60 = 0
Collect like terms
- 2j = 60 - 15
