-------------------------------------------- Define x: -------------------------------------------- Let the tie be x Tie = x Shirt = x - 4.02
-------------------------------------------- Construct equation : -------------------------------------------- The sum of the shirt and tie is $75.62 x + x -4.02 = 75.62 2x - 4.02 = 75.62 2x = 79.64 x = $39.82
-------------------------------------------- Find the cost of tie and shirt : -------------------------------------------- Tie = x = $39.82 Shirt = x - $4.02 = $39.82 - $4.02 = $35.80
---------------------------------------------------------------------------------------- Answer: The price of the short is $35.80 ----------------------------------------------------------------------------------------
<span>The total weights must add upto 50 lbs. Let x represents the number of 3 lb weights and y represents the number of 10 lb weights, we frame an equation as 3x + 10 y =50. Because there are some 10 lb weight and some 3 lb weights but we dont know the exact number.</span>
