You deposited 8500 dollars in a saving account that earns a simple interest rate. what interest rate do you need to be paid if y

V125BC [204]

Answer:

23.75%

Step-by-step explanation:

Use formula

$I=P\cdot r\cdot t,$

where

I = interest,

P = principal,

r = rate (as decimal),

t = time (in years).

In your case,

$I=\$8,500\\ \\P=\$10,093.75\\ \\t=60\text{ months}=5 \text{ years}$

Substitute:

$10,093.75=8,500\cdot r\cdot 5\\ \\r=\dfrac{10,093.75}{8,500\cdot 5}=0.2375=23.75\%$

SIZIF [17.4K]

Answer:

correct answer = 90%

Step-by-step explanation:

Let x be the percent of the question did she answer correctly.

Given:

An engineering student answered 81 questions correctly on a 90 question test.

Find the percent of the question did she answer correctly.

Solution:

Percentage formula is given below

% answer $=\frac{correct\ answer}{total\ questions}\times 100$

% answer $=\frac{81}{90}\times 100$

% answer $=\frac{81\times 100}{90}$

% answer $=\frac{81\times 10}{9}$

% answer $=9\times 10$

% answer $=90$

correct answer = 90%

Therefore, she answered 90% correctly.
