Answer: B. 8/100
Let's give 5/10 a denominator of 100 since 58/100 does, so they have common denominators:
5/10 * 10 = 50/100
Now, we can subtract 50/100 from 58/100 to find the unknown fraction:
58/100 - 50/100 = 8/100
This gives us an answer of,
B. 8/100
Given:
Grocery store: 8 ounces of blueberries = $2.80
Farmer's market : 14 ounces of blueberries = $4.20
1 pound = 16 ounces.
Unit rate: per ounce
Grocery store: $2.80 ÷ 8 oz = $0.35 per ounce
Farmer's market: $4.20 ÷ 14 oz = $0.30 per ounce
Unit rate per pound
Grocery store: $0.35 per ounce * 16 ounces = $5.60 per pound
Farmer's market: $0.30 per ounce * 16 ounces = $4.80 per pound
The formula for this problem is A=P(1+(r/n))^nt.
A is what you're trying to find. P=400 r=0.06 t=3 n=1, since it's compounded once per year.
Now plug in those values to get A=400(1+(0.06/1))^1*3
I get an answer of $476.41
