Answer:
Step-by-step explanation:
You have the formula written correctly, so now we just need to fill it in with what we have. Our principle, or initial investment, is 21,000; our interest rate of 4.6% as a decimal (always as a decimal!) is .046; and our interest earned is 900. We need to find t. Setting up with what we have:
21000(.046)(t) = 900 and
966t = 900 and
t = .931 years
.9 of a year is the same as 10.8 months or so.
7.5
Explanation:
11-3.5=
Take 3 away form 11 and then get 8 then subtract.5 and you are left with 7.5
$79.99 x 12% = $9.5988 merchandise discounted
$79.99-$9.5988 = $70.3912 rounded $70.39 sales merchandise
$70.39 x 6.75%= 4.7513 sales tax
$70.39 + $4.7513= $75.1413 or
the answer rounded is: $75.14
