a= 16x+16

b= 40x + 15

Step-by-step explanation:

We know that perimeter of a rectangle is

2(l + b)

So therefore

2(8x + 3 + 5) = a

=  > 16x+ 6 + 10 = a

=  > 16x + 16 = a

Answer= A) that is perimeter is 16x+16

We know that area of a rectangle is l×b

So therefore

(8x + 3) \times 5

= 40x + 15

Answer = b) that is area is 40x + 15

Amount Financed: $2,650
Finance Charge: $484.69
Number of Payments: 36

(Finance Charge)/(Amount Financed)*100$=($484.69)/($2,650)*100$
(Finance Charge)/(Amount Financed)*100$=(0.1829)*100$
(Finance Charge)/(Amount Financed)*100$=$18.29

In the row of number of Payments 36, we look for:
(Finance Charge)/(Amount Financed)*100$=$18.29, and we see to which annual porcentage rate it corresponds in the first row

Answer: 11.25%

If the sales tax in Alabama is 4 percent and a $20.00 purchase is made. What is the sales price? What is the total purchase pric
mihalych1998 [28]
Hello there! So first off, let's find the tax. In order to find the tax of an item, all you have to do is multiply the price by the percentage, because the tax is the portion of the price. The tax is 4%. Let's solve. 20 * 4% (0.04) is 0.8. The tax is $0.80. Let's add that to the purchase price. 20 + 0.80 is 20.80. That's the total purchase price. Here are the answers easier to read.

Sales tax: $0.80
Total price: $20.80
