A bank manager wants to encourage new customers to open accounts with principals of at least $2 comma 500. He decides to make a

prisoha [69]

Answer:

To earn $10 in 1st month, the principal must be $4,000.

No, the poster cannot claim that "Open an account of $2 comma 500 and earn at least $10 interest in 1 month!".

Step-by-step explanation:

We have been given that a bank manager wants to encourage new customers to open accounts with principals of at least $2,500. He decides to make a poster advertising a simple interest rate of 3%. We are asked to find the principal to advertise that one can earn $10 the first month.

We will use simple interest formula to solve our given problem.

$I=Prt$ , where,

I = Amount of interest,

P = Principal amount,

r = Annual interest rate in decimal form,

t = Time in years.

$r=3\%=\frac{3}{100}=0.03$

1 month will be equal to $\frac{1}{12}$ .

$\$10=P\cdot0.03\cdot \frac{1}{12}$

$\$10=0.0025P$

$\frac{\$10}{0.0025}=\frac{0.0025P}{0.0025}$

$P=\$4000$

Therefore, to earn $10 in 1st month, the principal must be $4,000.

Now, we will check if an account of $2,500 can earn at least $10 interest in 1 month.

$I=\$2500\cdot 0.03\cdot \frac{1}{12}$

$I=\$6.25$

Since the account earns an amount of $6.25 in one month, therefore, the poster is not true.

Given that the triangles are similar how to find x

alexdok [17]

So if they are similar then just try to figure out which two sides correspond to each other from the first and then the second triangle.

See how in the above example I did 20 and 5 not 20 and 14 or 20 and 3.5 because they do not correspond with one another.

Then figure out, is x on the mama or baby shape and either multiply the number received from all proportions or divide.

Multiply : small to big ( # missing on the bigger one )

Divide : big to small ( # missing on the smaller one)
