Answer:
The number of short sleeve sold was 76
Step-by-step explanation:
Let
x ----> the number of short sleeve sold
y ----> the number of long sleeve sold
we know that
[tex]\frac{x}{y}=\frac{4}{10}[/tex]
[tex]x=\frac{4}{10}y[/tex] -----> equation A
[tex]x+y=266[/tex] -----> equation B
substitute equation A in equation B
[tex]\frac{4}{10}y+y=266[/tex]
solve for y
[tex]\frac{14}{10}y=266\\\\y=266(10)/14\\y=190[/tex]
Find the value of x
[tex]x=\frac{4}{10}(190)=76[/tex]
therefore
The number of short sleeve sold was 76
