Can somebody answer numbers 13 and 14 all of the parts. ignore all the other writing. i appreciate anyone who can .

13.

a. $300 interest paid (Total amount with interest - Initial amount)

b. $3300 total amount paid (Total amount with interest)

14.

a. $3360 total amount paid (Total amount with interest)

b. $140 paid monthly (3360 ÷ 24 (24 months in 2 years))

c. Credit card (3300 to pay versus 3360 to pay; credit card $60 cheaper)

Step-by-step explanation:

Use the simple interest formula when answering these questions:

A = P(1 + rt)

Where:

A = Total Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

r = Rate of Interest per year in decimal; r = R/100

R = Rate of Interest per year as a percent; R = r * 100

t = Time Period involved in months or years

For example:

13.

a. P = 3000, r = 20% = 0.2, t = 6 months = 0.5 years

A = 3000(1 + (0.2)(0.5))

A = 3300

3300 - 3000 = 300

$300 interest paid

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =    

hope this you and
