If Martin deposited \$2,11 into an account and earned $750 of interest over 5 years, how much was the interest rate?

5.90% much was the interest rate .

Step-by-step explanation:

Here we have , If Martin deposited \$211 into an account and earned $750 of interest over 5 years, We need to find how much was the interest rate . Let's find out:

Let us suppose that interest rate was x%  per month! So , Amount of money he earned as interest per month :

⇒

Now , For one year( 12 months ) he earned :

⇒

∴For five year he earned :

⇒

According to question , he earned $750 of interest over 5 years i.e.

⇒

⇒

⇒

⇒

Therefore , 5.90% much was the interest rate .

The interest rate is 7.1%

Step-by-step explanation:

It is given that,

To find the interest rate :

The formula used here is given by,

Interest = P× r× t

where,

Now, substituting P= $211 , t= 5 and  I = $750

⇒ 750 = 2110 × 5 × r

⇒ 750 = (10550×r)

⇒ 750 ÷ 10550 = r

⇒ r = 0.071

The rate should be represented in the percentage, therefore,  multiply it by 100.

Interest rate = 0.071 × 100

Rate = 7.1 %

∴ The interest rate is 7.1%

step-by-step explanation:

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
