Answer:
Step-by-step explanation:
Since this is simple interest we will need to break down these numbers in variables, so we can make an algebraic expression.
[tex]\mathrm{Simple\:interest}= \frac{p*r*t}{100}[/tex]
P= Represents the principal. The principal is the money or amount of something used to buy something with a paid "tax" of a rate and a time.
R= Represents the interest rate. If you do not know where you can find the "r" an example is in this question, it is, "She will pay an 8% interest rate." The interest rate is always in percent.
T= Represents time. Time means days, months, or even years or decades.
1. Plug in the numbers
[tex]\mathrm{Simple\:interest}= \frac{2,000*8*18}{100}[/tex]
This is saying that simple interest is p times r times t. Once you find your answer, divide it by 100 to get your answer. You divide by 100 because it is part of whole and usually whole is 100% maybe of a battery and etcetera.
2. Multiply & Divide
[tex]\\\\\\\\\mathrm{Multiply.\:You\:want\:to\:find\:the\:product\:of\:lower\:numbers\:first.} \\8;18 \\\\\frac{2,000*8*18}{100}\\\\\frac{2,000(8*18)}{100}\\\\\frac{2,000*144}{100}\\\\\frac{288,000}{100}\\\\= \mathrm{Jamie\:will\:pay}\\\\2,800\\\\ \mathrm{in\:interest.}[/tex]
