Mara found the length of time of an investment. The principal of the investment was $4,300, the interest rate was 6.2 percent, and the interest was $2,666. Mara made an error in her work. I = p r t. 2666 = (4300) (0.062) t. 2666 = (266.6) t. StartFraction 266.6 over 2666 EndFraction = t. 0.1 = t. What was Mara's error? Mara did not substitute the values from the problem into the formula correctly. Mara did not multiply correctly. Mara did not divide correctly. Mara divided when she should have multiplied.

Mara did not divide correctly.

Step-by-step explanation:

Mara found the length of time of an investment. The principal of the investment was $4,300, the interest rate was 6.2 percent, and the interest was $2,666. Mara made an error in her work. I = p r t. 2666 = (4300) (0.062) t. 2666 = (266.6) t.StartFraction 266.6 over 2666 EndFraction = t. 0.1 = t. What was Mara's error?

Correct solution

I = PRT

Hence:

2666 = 4300 × 6.2% × t

t = 2666/4300 × 6.2%

t = 2666 ÷ 266.6

t = 10 years

Hence, Her error was:

Mara did not divide correctly.

For them lazy bones it's C. Maya did not divide correctly

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )
