Answer: $358.8 to the nearest tenth
Step-by-step explanation:
Compound interest is calculated by Where: A = P(1 + r)t
Where P= 300, r= 12% = 0.12, t= 1.5 years
Slot in the figures
300 (1 + 0.12) 1.5
300 (1.12) 1.5
300x 1.12
336e1.12
A = $ 358.84
Define the variables:
y= amt. of $ saved by Darren's friend
x= # of weeks
Darren adds $40 to his savings EVERY WEEK. He also started with $120, so the equation is:
y=40x+120
Answer:
2,052,086,400.
Step-by-step explanation:
Permutation
Pr = n! / (n-r)!
30P5 = 30! / (30-5)
30P5 = 30x29x28x27x26x25! / 25!
(Just cancel the 25! on the numerator and denominator for easier solving.)
30P5 = 30x29x28x27x26
30P5 = 17,100,720.It is not the final answer because we can still arrange the 5 winners.
5! = 5×4×3×2×1 = 12017,100,720 × 120 = 2,052,086,400
Answer: 4/5
Step-by-step explanation:
1. split each candy bar into fifths
