Given : John bought 2 pairs of short and 1 pair shirt for P2,000.00 on monday. The next day he decided to buy his brothers 4 pairs of shorts and 3 shirts worth P4,600.00.
To Find : How much is each pair of shirt and short?
Solution:
Cost of pair of short = A P
Cost of pair of shirt = B P
2 pairs of short and 1 pair shirt for P2,000.00
=> 2A + B = 2000 Eq1
4 pairs of shorts and 3 shirts worth P4,600.00.
=> 4A + 3B = 4600 Eq2
Eq2 - 2 * Eq1
=> 4A + 3B - 4A - 2B = 4600 - 4000
=> B = 600
2A + 600 = 2000
=> 2A = 1400
=> A = 700
Cost of pair of short = 700 P
Cost of pair of shirt = 600 P
