Answer:

a) $160

b) $116.50

Explanation:

a) Let the original price of the yellow bicycle be $x.

Since both has the same original price,

original price of yellow bicycle= 100% x

original price of green bicycle= 100% x

Discounted price of yellow bicycle

= (100% -25%) x

= 75% x

Discounted price of green bicycle

= (100% -30%) x

= 70% x

Difference in cost

= 75%x -70%x

= 5% x -----(1)

From 2nd paragraph:

Discounted price of yellow bicycle

= Kyreen's money +3.50

Discounted price of green bicycle

= Kyreen's money -4.50

Difference in cost

= (Kyreen's money +3.50) -(Kyreen's money -4.50)

= Kyreen's money +3.50 -Kyreen's money +4.50

= 3.50 +4.50

= 8.00 -----(2)

Equating (1) and (2) together:

5% x= 8.00


(5)/(100) x = 8


x = 8 / (5)/(100)


x = 8 * (100)/(5)

x= 8 ×20

x= 160

Thus, the original price of the yellow bicycle is $160.

_______

b) Amount Kyreen has at first

= discounted price of yellow bicycle -$3.50

= 75%($160) -$3.50

= $120 -$3.50

= $116.50
