Victor calculates the percentage interest rate he needs to make twenty dollars in simple annual interest over 2 months on a deposit of one thousand dollars. Where did he go wrong?

I equals p times r times t; twenty equals one thousand times r times two; r equals zero point zero one; r equals one percent

He applied the principal and interest to the wrong variables.

He should have divided 2 by twelve to get the value for t.

He misrepresented the earned interest with the final balance.

He should have multiplied r by one hundred to get the interest rate as a percentage.

do we have to do calculation and working here or it's just a MCQ?

anonymous · Answer

No I don't think so. It's a multiple choice question. What is Victor's error? I need the right answer.

anonymous · Answer

FIrst of all ther's a typo:

$$I != P \times R \times T$$
$$I = \frac{ P \times R \times T }{ 100 }$$

anonymous · Answer

There is?

anonymous · Answer

don't believe it then google it

anonymous · Answer

No I believe you so then what is the answer if there is a typo?

2nd option

Thank you so much! :)
May you help with a little more? :S

anonymous · Answer

but I personalyy believe

$$20  != \frac{ 1000 \times 1 \times 2 }{ 100 * 12 }= 10 /6 = 5/ 3$$

anonymous · Answer

Fayed tipped the pizza delivery driver three dollars for pizzas that cost eighteen dollars. Approximately what percent did he tip the driver? Round your answer to the nearest percent.

three percent

six percent

fifteen percent

seventeen percent

anonymous · Answer

very simple question:

I ssume that you mean the percent is approcimated on the basis of the CP of pizza(yummy:P)

Therefore:

$$= \frac{ 3 }{ 18 } \times 100 = \frac{ 100 }{ 6} = \frac{ 50 }{ 3 } = 16.6 \approx 17$$

Ans 17%
