Answer:448.5
Step-by-step explanation: first you have to see what 50% of 299 is so you do 299/2=149.5 so now they are marking it up so you do 299+149.5 =448.5

<h3>
Answer:</h3>
B) 6 hours
<h3>
Step-by-step explanation:</h3>
Let h represent the total trip time. Then h/2 is the time spent traveling at each speed. The distance covered is ...
... distance = speed · time
The sum of the distances in each mode is the total distance.
... 1020 = 55·h/2 +285·h/2
... 2040 = h·(55+285) . . . . multiply by 2
... 2040/340 = h = 6 . . . . . . . divide by the coefficient of h
The trip took a total of 6 hours.
There’s 180° in any triangle, so you can solve by doing 180-102-55= 78-55= 23° as our final answer.
Answer:
- $223.84 at the end of the month, or
- $223.31 at the beginning of the month
Step-by-step explanation:
The annuity formula is used for this.
A = P((1+r/12)^(12t) -1)/(r/12)
gives the balance A resulting from payments P being compounded monthly at annual rate r. (Payments are made at the end of the month.)
50,000 = P((1 +.028/12)^(12·15) -1)/(0.028/12) ≈ 223.378772P
P ≈ 50,000/223.378772 ≈ 223.84
To achieve the desired balance, Tometeo must deposit $223.84 at the end of every month.
_____
If Tometeo makes his deposits at the beginning of the month, then the amount is less by the interest earned for the month:
$223.84/(1 +.028/12) ≈ $223.31 . . . . beginning of the month deposit amount
