In September, the ratio of the amount Ray spent and the amount he saved was 4:1. In October, he got a salary raise. He increased his spending by 25% but save the same amount. Find the new ratio. Is it 5:1?
The School Subject "central middle" is unknown to me. Sorry.
amount spent = 4x
amount saved = x
after increase = 1.25(4x) = 5x
amount saved = x
so new ratio = 5x: x = 5:1
you are correct
To find the new ratio, we need to calculate the amounts Ray spent and saved in both September and October.
Let's assume that in September, Ray spent an amount represented by 4x and saved an amount represented by 1x. This gives us a ratio of 4:1 for September.
In October, Ray got a salary raise. Let's denote the new amount Ray saves as 1x (since he saved the same amount as in September). He increased his spending by 25%, which means his new spending amount is 4x + 0.25(4x) = 5x.
So, the new ratio of spending to saving in October is 5x:1x, which can be simplified to 5:1.
Therefore, based on the given information, the new ratio is indeed 5:1, confirming your answer.
