Answer:
10.99%.
Step-by-step explanation:
We have been given that the Smiths bought new furniture that cost $3,298.00. The store offered them an option of putting $600 down and making equal payments of $300 a month for 10 months.
First of all, we will find amount paid by down-payments in 10 months.

Total amount paid by Smiths:
.
Now we will find amount paid in interest by subtracting initial amount from total amount.

10 months = 10/12 year =5/6 year.
Now, we will use simple interest formula to solve for interest rate.




Therefore, the annual interest rate is 10.99%.
Remember the cost cannot be a number lesser than zero. so the domain must be such that the total cost C(m) is not negative. Also the range will always be 0.5 and above provided our domain is greater than or equal to zero.
Perimeter = sum of all the sides
let x = one side
longer side = x + 10
Perimeter = x + x + x + x + 10
62 = 4x + 10
4x = 52
x = 13
Longer side = 23
Area = (10+23)x2/10
= 6.6
Answer:
this is geometry?
Step-by-step explanation:
Answer:
76 *5 = 380 $
184 - 76 = 108
108 * 4 = 432
432 + 380 = 812
