Answer:

-80

Step-by-step explanation:

We have to do the parentheses first because it's part of PEDMAS.

-2x-5= 10

Next, we take 10 times -8

-8 x 10= -80

There you go! Hope this helps!

-8 • (-2x) -8 • (-5) * • = multiplication *
the solution would be:
16x + 40

Maria is buying a car for $18,510. She will finance $13,000 of it with a 3-year loan at 2.8% APR. What will her monthly auto pay
Eva8 [605]

<u>Answer-</u>

<em>Maria's monthly payment will be </em><em>$376.91</em><em> </em>

<u>Solution-</u>

Maria is buying a car worth of $18,510, but she will finance only $13,000 of it with a 3-year loan at 2.8% APR.

We know that,

\text{PV of annuity}=P[\dfrac{1-(1+r)^{-n}}{r}]

Here,

\text{PV of annuity=13000},\\\\\text{P=??},\\\\\text{r = 2.8\%\ annually}=\frac{2.8}{12}\text{\%\ monthly}\\\\\text{n=3 years=36 months}

Putting  the values,

\Rightarrow 13000=P[\dfrac{1-(1+\frac{2.8}{1200})^{-36}}{\frac{2.8}{1200}}]

\Rightarrow 13000=P\times 34.4909

\Rightarrow P=\dfrac{13000}{34.4909}

\Rightarrow P=376.91

Therefore, her monthly payment will be $376.91

ryzh [129]
