Hi all

For the life of me, I am always having problems with these kind of problem sums. Hope one of you can help :

After spending an equal amount of money, Cally had twice as much money as Anne.
How much money did each of them spend?

Ans : \$135

Thanks a lot!

200 - 165 = 35

35 x 2 = 70

Cally has \$70 in the end.

200 - 70 = 130
They each spent \$130.

Concept -- Constant Difference

Hi Veronica, don't trust all answers in the answer sheet. Some of them are wrong

Hi Angie, yes the answer is 130.

Hi Angie, can you explainwhy the difference of 35 is actually half of Cally's final amount? So sorry but need to know the concept so that i can explain to my kid.. my maths is terrible.
thanks
