The sum of the ages of Levi and Monique is 76 years. 8 years ago, Levi's age was 3 times Monique's age. How old is Levi now?

andreev551 [17]

Answer:

Levi is 53 yrs now

Step-by-step explanation:

sum = 76yrs

Levi = 3x -8

Monique = x - 8

8yrs ago

sum= 76 - 8 - 8( the two 8s are from each of the two brothers).

= 60yrs

Levi=3x

Monique=x

3x + x = 60

4x = 60

x = 15yrs

Levi = 3x

= 15 x 3

= 45 yrs(8yrs ago)

now = 45 + 8

= 53yrs now

Monique = x

= 15

now = 15 + 8

23yrs now

Zene deposited $50 in a savings account earning 5% interest, compounded annually. To thenearest cent, how much will he have in 3

JulsSmile [24]

Answer:

$\$57.88$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=3\ years\\ P=\$50\\ r=5\%=5/100=0.05\\n=1$

substitute in the formula above

$A=50(1+\frac{0.05}{1})^{1*3}$

$A=50(1.05)^{3}$

$A=\$57.88$
