Answer:
it takes approximately 11 years and 3 months (11.4 years) for Belinda's investments to double.
Step-by-step explanation:
To calculate the time it takes for Belinda's money to double, we will use the simple interest formula as shown below:
Simple interest = P × R × T
where:
P = principal = $800
R = Rate in decimal = 8.75% = 0.0875
T = time = ???
simple interest = $800 ( her money doubles)
∴ 800 = 800 × 0.0875 × t
800 = 70 × t
∴ t = 800 ÷ 70 = 11.4 years. (11 years and 3 months)
Therefore after approximately 11 years and 3 months, Belinda's investments doubles
The answer is 3.42 x 10^6 because we moved the decimal 6 places to the left. Hope this helps:)

Answer:
tip = 3.07
final bill = 18.40
Step-by-step explanation:
To find the tip, we take the percent times the bill
tip = 20% * 15.33
.20 *15.33
3.066
Rounding to the nearest cent
3.07
The final bill is the tip plus the bill
final bill = 15.33+3.07
18.40
