Question

a pair of shoes cost 20 more than 14 times the cost of pair of socks.9 pairs of shoes cost as much as 130pair of socks ,how much does each cost?

Answer 1

Let shoes cost be=y

Let the cost of socks be=X

Given,

y=14x+20

Also given,

9y = 130x

y=(130/9)x

Therefore,

(130/9)x= 14x+20

130x =9(14x+20)

130x = 126x+180

4x = 180

x=45=cost of socks

y=(130/9)*45=650
