Annika's older cousin bored $800 to repair her car. she will pay off the loan after 2 years buy paying back the principal plus 4.5% simple interest each year. how much will she spend in interest?

The equation below is provided:

$800 = principal amount borrowed/loaned
4.5% = interest per year
2 years = terms of payment

You need to know how much is the interest per year.
$800 * 4.5% = $36

Then, multiply the amount to the terms of payment to know the total amount of the interest to be paid.
$36 * 2 years = $72

The correct answer for the amount that Anika will spend for the interest is $72.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

answer: the function g(x) has the greatest slope.
