The student council sold long sleeve shirts for $12.50 and short sleeve shirts for $10.
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the cost of long sleeve and y represent the cost of short sleeve, hence:
24x + 18y = 480 Â Â (1)
Also:
34x + 25y = 675 Â Â (2)
From both equations:
x = 12.5, y = 10
The cost of long sleeve shirts was $12.50 while short sleeve was $10 each.
