The answer is. $1500.
Let x represent the amount invested at 5%, then is the amount invested at 8%, and is the amount invested at 6%. Since the total return is $1270:
let money invested at 5%= x
money invested at 6%
= 20000- (X+X-1500)
21500-2x
Total interest for 1 year.
x×5/100+ (x-1500)×8/100+(21500-2x)×6/100 = 1270
5x/100+8(x-1500)/100+(21500-2x)6/100=1270
5x+8x-12000+129000-12x = 127000
x+117000 = 127000
x = 10000
money invested at 8%
=21500-2×10000
= 1500.

Answer:
£2025
Step-by-step explanation:
increasing by 35% means the answer will be 135% of the original. so multiply the 1500 by 1.35. 1500x1.35=2025, so the answer is £2025.
there's alternative methods if you find them easier. you can multiply it by 135 and then divide it by 100, or you can multiply it by .35 and add that to the original, or you can multiply it by 135, divide it by 100, and add it to the original. i just find the first one the easiest! this works for any percent increase OR decrease (if it's a decrease, subtract the percentage from 100%).
