Tim worker buys a satellite dish for $329.99. he pays 10% down and takes an installment loan to complete the purchase. he makes 12 payments which include his principal and a $40.00 finance charge. what is the apr on his loan?

tim will pay ($329.99 x 10%) or $ (to the nearest whole number) for his down payment.

he will finance ($329.99 - down payment) or $.

tim will repay finance amount ÷ 12 plus $40.00 ÷ 12 or monthly payment of $.

at the end of one year tim will have paid monthly payments totaling $.

the apr = finance charge for one year ÷ amount financed = % (to the nearest tenth).

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
