Got the equation just don’t have a calculator to do the rest

Answer:
$159.985 that is the answer i got by using this equation [tex]21\left(1-0.0858\right)\frac{100}{12}[/tex]
$159985 using this equation [tex]21000\left(1-0.0858\right)\frac{100}{12}[/tex]
$9944.03786 using this equation [tex]21000\left(1-0.0858\right)^{\frac{100}{12}}[/tex]
$9.94403 using this equation [tex]21\left(1-0.0858\right)^{\frac{100}{12}}[/tex]
Step-by-step explanation:
I couldnt quite understand the equation, so i done it multiple ways. Hope this helps
Step-by-step explanation:
[tex]y=21000(1-0.0858)^\frac{100}{12}[/tex]
[tex]y=21000(0.9142)^\frac{100}{12}[/tex]
[tex]y= 9944.037[/tex]
So, after a 100 months, the car's worth would be $9,944.04
