Can Anyone Work This Maths Problem Out For Me?

I have a Game Reward Card....


They reward you with 10 points every 拢1 you spend


Every 1000 points give you 拢2.50 credit





How much have I spent to get 拢65 worth of credit?Can Anyone Work This Maths Problem Out For Me?
You have spent 拢2600 to get 拢65 credit





拢2600 gets you 26000 Points





26,000 Points earns you 26 times (拢2.50)





拢2.50 x 26 = 拢65 worth of creditCan Anyone Work This Maths Problem Out For Me?
1000/10= 100


65/2.50=26


26 by 100= 2600pounds


Ans: 拢2600 Q.E.D
拢2.50 = 1000 points. 拢65 is 26 times this amount so this gives you 26000 points credit. As the ratio of points to pounds is 10:1 then this equals 拢2600.
1000 points gets 拢2.50 credit.


To get 拢65 of credit, you had to have 65/2.50 = 26 times 1000 points = 26000 points.


To get that many points, you had to spend 26000/10 = 2600 times 拢1 = 拢2600.
拢2.50 represents 拢100 you've spent.


拢2.50 goes into 拢65 26 times.





You've spent 拢2,600!





(I think)
65 pounds
You would have spent alot, and if my calculations are right then u have spent 拢26000
拢2600.00





拢2.50 goes into 拢65 26 times, so you must have 26000 points, divide by 10 = 2600
1000/10 = 拢100 spent for 2.50 back





65/2.5 *100 = 拢2600
拢26,000!!
(65*10/1000) * 2.5 = 1.625 credit
You have to spend 2600 Pounds to earn 65 Pound credit.
拢2600 My guess is it's not worth it
2600
2600.00
