Answer: the price of a T-shirt is $17.5
the price of a pair of jeans is $5
Explanation:
Let x represent the price of one T shirt.
Let y represent the price of one pair of jeans.
James bought two T-shirts and one pair of jeans at an online store and paid $40. This means that
2x + y = 40- - - - - - - - - - - - - 1
A month later, the same store sold the T-shirts and jeans at a 50% discount from their original prices. James bought two T-shirts and five pairs of jeans for $60. Assuming the base prices of the T-shirts and the jeans are the same on both occasions, This means that
2x + 5y = 60- - - - - - - - - - - -2
Subtracting equation 2 from equation 1, it becomes
- 4y = - 20
y = - 20/ - 4
y = 5
Substituting y = 5 into equation 1, it becomes
2x + 5 = 40
2x = 40 - 5 = 35
x = 35/2
x = 17.5
