Darryl deposits $ 1,500.00 into a savings account that has a simple interest rate of 2.7% Lori deposits $ 1,400.00 into a savings account that has a simple interest rate of 3.8% If no other transactions are made whose account will have more money after 10 years?

Answers

Answer:

Daryl

He deposits $1,500 at an interest rate of 2.7%

We now turn the percentage into a decimal 2.7%--->0.027

We multiply $1,500 x [tex]1.027^{10}[/tex] to get 1,957.92

Lori deposits $1,400 at an interest rate of 3.8%

We once again turn the percentage into a decimal 3.8%--->0.038

We multiply $1,400 x [tex]1.038^{10}[/tex] to get 2032.83

Meaning Lori has more at the ned of the 10 years

1. For a party, Susan estimated there would be 14 people in attendance, but only 12 showed up. What was the percent error in her estimation?

2. Find the percent error in this situation:
Estimated value: 231
Actual value: 215

3. Find the percent error in this situation:
Experimental value: 16.5 sec
Theoretical value: 17.1 sec

4. Find the percent error in this situation:
Estimated value: 1081
Actual value: 1150

Answers

The formula for percent error is:

((Approximate value -  exact value) / exact value) x 100

1) 14-12 = 2

2/12 = 0.1666

0.166 x 100 = 16.7%  (Rounded to nearest tenth)

2) 231 - 215 = 16

16/215 = 0.74419

0.74419 x 100 = 7.4419% ( Round as needed)

3) 17.1 - 16.5 = 0.6

0.6/16.5 = 0.36364

0.36364 x 100 = 3.6364% (Round off as needed)

4)  1081 - 1150 = -69

-69/1150 = -0.06

-0.06 x 100 = -6% = 6% error

Answer:

1) 85.7%

2) 93%

3) 96.5%

4) 94%
