Hi everybody! I am stuck with this maths questions again.
Kenneth and Joanna were each given some money. If Kenneth spent half of the amount spent by Joanna, he would have $2400 left. If Kenneth spent twice as much as Joanna, he would would still have $900 left when Joanna had spent all her money.
a) How much money was given to Kenneth?
b) How much less money than Kenneth did Joanna have?

Hey Shirley,
Following pls find the worked solution:
<Cond1>
**<1u>< 2400 >
K 
J 
**<2u>
<Cond2>
**<4u>< 900 >
K 
J 
**<2u>
*Gap**< 1500 >
*Diff***< 3u >
3u > 1500
1u > 500
(a) K (at first) = 1u + 2400 > 500 + 2400 = $2900
(b) J = 2u > 2 x 500 = $1000
****Less = 2900  1000 = $1900
Joanna had $1900 less than Kenneth
===============================================
Trust the above helps.
Do let me know if this is different from the answerkey.
Cheers,
Edward
