You estimate the product by rounding 67 up to 70, and 73 down to 70 to get a product of 4900, which is 9 away from 4891 which is the product of 67 and 73
Total = principal * (1 + rate / n)^(n * years)
where "n" is the number of compounding periods per year
Total = 1,500.00 * (1 + .025/4)^(4 * 4)
Total = 1,500.00 * ( <span><span><span>1.00625
</span>
</span>
</span>
)^(16)
Total = 1,500.00 *

Answer:
A-The first question
Step-by-step explanation:
Try using Math.way next time!
A+b+c=130
a,b,c ip cu 2,3,4
2a=3b=4c=k
a=k/2
b=k/3
c=k/4
k/2 + k/3+ k/4= 130 aducem la acelasi numitor (12)
6k+4k+3k=1560
13k=1560
k=120
a=120/2=60
b=120/3=40
c=120/4=30
