Answer:
14:2 - 14 parts water and 2 parts salt
Step-by-step explanation:
The original ratio was 7:1. So, that means if you added another part to the salt it would make 2. That means that the 7 parts of water would become 14 parts. Since the ratio of the salt part was doubled from 1 to 2, you would have to do the same with the water ratio part. Hoped this helped!
Ok so what we need to find is 3 years of the simple interest so let’s get to it!
Ok so we found the principal price which is 250.00
And our rate is going to be 2.85%
A=P(1+rt)
Therefore the answer is going to be A=$271.38, therefore from the simple interest on a principal of $250.00 at a rate of 2.85% per year for 3 years is $271.38.
I think the answer is d or b if im wrong sorry hope this helped tho :p
