✔ 最佳答案
一條圍巾既價錢係襪既5.6倍,,而皮帶既價錢係襪既3.2倍
皮帶既價錢係59.2
A scarf costs 5.6 times as a pair of socks.A belt costs 3.2 times as a pair of socks. The belt costs $59.2.

a). 設x為襪既價錢:
let x be the socks cost :

3.2x=59.2
x = 59.2/3.2
x = 18.5$

b). 設y為圍巾的價錢:
let y be the scarf cost:
5.6*18.5=x
x=103.6
所以圍巾的價錢為皮帶的
So the cost of scarf as the cost of belt is
103.6/59.2
=1.75倍
(=1.75 times)

Price: Scarf = 5.6 x Socks
Price: Belt = 3.2 x Socks

Belt = $59.2

a) Price: 59.2 = 3.2 x Socks
. Socks = 59.2 / 3.2
. Socks = $18.5

b) Price: Scarf = 5.6 x 18.5
. Scarf = $103.6

Scarf Cost: $ 103.6
Belt Cost: $59.2

Therefore 103.6 / 59.2 = 1.75 times
because Belt(price) x 1.75 = Scarf(price)
