To find: what is the price of one shirt?
Price of one shirt is $15.
Given: Z spends $120 on 3 pairs of pants and 4 shirts and D buys 2 pairs of pants and 3 shirts and spends $85.
Concept Used:
Elimination method of solving linear equation in two variables.
Calculation:
Let the price of one pant be
Now, forming linear equation on the given situations:
Z spends:
And D spends:
Multiply equation (i) by 2 and equation (ii) by 3:
subtract equation (iii) from equation (iv):
Therefore, the price of one shirt is $15.
Conclusion:
The price of one shirt is $15.
