Question 1011579: A pair of shoes costs £5 more than twice the cost of a tie. If Grant buys two pairs of shoes and three ties, the total cost is £255. Find the cost of:
a) a tie
b) a pair of shoes
Answer by harpazo(655) (Show Source): You can put this solution on YOUR website!
One pair of shoes = 2x + 5
One tie = x
2(2x + 5) + 3x = 255
4x + 10 + 3x = 255
7x + 10 = 255
7x = 255- 10
7x = 245
x = 245/7
x = 35
One tie sells for 35£.
One pair of shoes sells for
2(35) + 5 = 75£.
I hope this helps.
