How many days will it take for a sum of $4,000 to earn $80 interest if it is deposited in a bank paying ordinary simple interest

Maksim231197 [3]

Answer:

It will take 146 days to earn an interest of $80.

Step-by-step explanation:

The simple interest formula is:

$I=\frac{P\times r\times t}{100}$

It is provided that:

I = $80

P = $4,000

r = 5% p.a.

Compute the time required as follows:

$I=\frac{P\times r\times t}{100}$

$t=\frac{I\times 100}{P\times r}$

$=\frac{80\times 100}{4000\times 5}\\\\=0.4\ \years\\\\=0.4\times 365\ days\\\\=146\ days$

Thus, it will take 146 days to earn an interest of $80.

Jun used x milliliters, or 90% percent, of his favorite bottle of hot sauce.

Verizon [17]

Answer:

The volume of the full bottle of Jun's favorite hot sauce in ml is $\frac{10x}{9}$ .

Step-by-step explanation:

Jun used x milliliters, or 90% percent, of his favorite bottle of hot sauce.

So, to find the volume of a full bottle of Jun's favorite hot sauce in milliliters, we can use the unitary method.

Then, 90% of the full bottle sauce is equal to x ml.

So, 1% of the full bottle sauce is equal to $\frac{x}{90}$ ml.

Therefore, 100% of the full bottle sauce is equal to $\frac{x}{90}\times 100 = \frac{10x}{9}$ ml.

Therefore, the volume of the full bottle of Jun's favorite hot sauce in ml is $\frac{10x}{9}$ . (Answer)
