Answer:

1:10 and 18

2:700 is the cost per each in short and 600 is the cost per each in the shirt..

Step-by-step explanation:

2:2000=700 +700 =1400 +600=2000 (2shorts cost 700 and 1 shirt cost 600 )

same with 4600= 700x4=2800

=600x3=+1800

4600

4 shorts cost 700 equals to 2800

3 shirts cost 600 equals to 1800
