Amy and simon bought a pair of shorts and some t-shirts. each pair of shorts cost the same amount, and each t-shirt cost the same.

•amy paid $60 for 1 pair of shorts and 2 t-shirts

•simon paid $75 for 1 pair of shorts and 3 t-shirts

what was the cost in dollars, of 1 pair of shorts

Cost of 1 pair of shorts was $30.

Step-by-step explanation:

Amy and Simon bought a pair of shorts and some T-shirts.

Amy paid $60 for 1 pair of shorts and 2 T-shirts

Simon paid $75 for 1 pair of shorts and 3 T-shirts

When we subtract  $60 from $75 = $15

Now we got the price of 1 T-shirt = $15

Cost of 2 T-shirts that Amy paid  = 15 × 2 = $30

1 pair of shorts = total cost - cost of 2 T-shirts

Cost of  1 pair of shorts = 60 - 30 = $30

Simon paid also paid for 1 pair of shorts and 3 T-shirts

30 + (3 × 15) = $75

Cost of 1 pair of shorts was $30

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
