No the correct way would be 3/5
I think you are correct
y=ab^x
1=ab^3
4=ab^5
divide the second equation by the first one, you get b^2=4, so b=2
plug b=2 either equation you get b=1/8

Answer:
2z and 4y
Step-by-step explanation:
We first have to use the second purchase to figure this out, if 4 bags of sand is $8. We have to divide 8 by 4, which we get $2. We use this to find the bags of pea gravel. Since you bought 3 bags, 3 times 2 is 6. We subtract 6 from 26 leading to 20 dollars. We also buy 5 bags of pea gravel so we have two numbers, 20 and 5. We divide 20 and 5 and we get 4 dollars for 1 bag of pea gravel. If this is not what you meant I apologise.
