Answer: There are 138 short sleeves t-shirts.
Step-by-step explanation:
Given : In August Emily's clothing store sold 460 shirts with the ratio of short sleeve to long sleeve being 3:7.
Let the number of short sleeves shirts be 3x and the number of long sleeves shirts be 7x.
Then, according to the given question, we have
[tex]7x+3x=460\\\\\Rightarrow\ 10x=460\\\\\Rightarrow\ x=46[/tex]
Now, the number of short sleeves shirt = 3(46)=138
Hence , there are 138 short sleeves shirts.
