Answer:
0.09
Step-by-step explanation:
So if you use the Simple interest equation it will begin with:
Interest total = Initial Amount of money x Interest rate per year x Years money is invested for.
Then substitute the values you have been given so:
$6300 = 7000 x Interest rate per year x 10.
This is simplifies to 6300 = 70,000 x Annual Interest rate
You can rearrange this to find the annual interest rate by dividing by 70,000:
Simplifying this would be:
= Interest rate.
The interest rate is 0.09.
Answer:
I think it is A but not 100% sure.
Step-by-step explanation:
X=number of gallons that she must order.
4 gallons-----------------3 weeks
(7 gallons + x)--------12 weeks
We solve this rule of 3.
(7 gallons +x)3 weeks=4 gallons*12 weeks
21 gallons weeks+3 x weeks=48 gallons weeks
3x weeks=48 gallons weeks - 21 gallons weeks
3x weeks=27 gallons weeks
x=(27 gallons weeks) / 3 weeks=9 gallons.
Solution: she must order 9 gallons more.
