Kayla buys two pairs of jeans for j dollars each and one shirt for 15 dollars. she has 60 dollars to spend. The equation 2j+ 15-60 can be used to find the cost of one pair of jeans​

Answer 1

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

• $\mathbf{\dfrac{2j}{2}= \dfrac{45}{2}}$
• j = 22.5

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