Cost of a shirt a shirt and a tie together cost $50 the shirt cost 30$ more than the tie what is the cost of shirt?
Cost of tie: x
Cost of the shirt: x + 30 ($30 more than a tie, so add 30 to the cost of tie)
Total Cost: $50
Equation:
Cost of Tie + Cost of Shirt = 50
(x) + (x+30) = 50
2x + 30 = 50
2x = 50 – 30
2x/2 = 20/2
x = 10 ⇒ cost of a tie
10 + 30 = 40 ⇒ cost of a shirt
