Answer:
Approx 2.61 years.
Step-by-step explanation:
Given that you decide to put $5,000 in a savings account to save for a $6,000 down payment on a new car.
That means A=6000 and P=5000
If the account has an interest rate of 7% per year and is compounded monthly,
Then r=7%= 0.07 and n=12 (monthly)
Now we need to find about how long does it take until you have $6,000 without depositing any additional funds.
So let's plug these values into compound interest formula and fine time t




![\ln\left(1.2\right)=12t\ ln[tex]\frac{\ln\left(1.2\right)}{12\ln\left(1.00583333333333\right)}=t](https://tex.z-dn.net/?f=%5Cln%5Cleft%281.2%5Cright%29%3D12t%5C%20ln%5Btex%5D%5Cfrac%7B%5Cln%5Cleft%281.2%5Cright%29%7D%7B12%5Cln%5Cleft%281.00583333333333%5Cright%29%7D%3Dt)
\left(1.00583333333333\right)[/tex]

Hence answer is approx 2.61 years.

Black keys=b
white keys=w
b+w=88|·9
w:b=13/9⇒9w=13b
9b+9w=792
13b+9b=792
22b=792|:22
b=36 keys
w=88-36
w=52 keys
