Question 1105950: Hi
in January joyce kept 80 percent of her salary of which she then gave 1/5 to her mum and saved the rest. The rest of her money was spent on food. In February she gave her mum 150 dollars more than the amount she had given in January. The amount given to her mum was then equal to the amount she saved. She spent the same amount on food in January and February.
What was her salary.
Book says 625 dollars I calculated 375 dollars.
thanks

You would get more out of this problem if you showed us how you got your answer, so we could show you what you did wrong. If you just tell us you got a different answer than the book, and we show you the right answer, and you take our answer and move on to other things, then you have learned nothing. That makes it a waste of both your time and ours.

Please if you submit more questions to us, SHOW us the work you have done.

Here is what I see....

January:
food: 20% (she kept 80%; the rest was spent on food)
to mum: 16% (1/5 of the 80% she kept)
saved: 64% (the other 4/5 of the 80% she kept)

February:
food: 20% (the same as January)
to mum: 16%, + $150 (150 dollars more than in January)
saved: 64%, - $150 (what she kept and didn't give to mum)

Then, though the wording of the problem is not clear, I think it says that in February the amount she saved was the same as the amount she gave to mum. So if her salary is x, then

I get a salary of $625 from that equation....
