kkurt [141]

Answer:

$257$

Step-by-step explanation:

We want to evaluate:

$5(41 - x) + ( - 7(y + x)$

for x=-2 and y=-4.

We substitute to get:

$5(41 - - 2) + ( - 7( - 4 + - 2)$

We now simplify to get:

$5(41 + 2) - 7( - 6)$

$5 \times 43 + 42$

$215 + 42 = 257$

Jenny invest $1000 at a rate of 12.5% that compounds annually for eight years the future value of the investment can be calculat

artcher [175]

Answer:

$\$2,565.78$

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 or Future 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

$t=8\ years\\ P=\$1,000\\ r=12.5\%=12.5/100=0.125\\n=1$

substitute in the formula above

$A=1,000(1+\frac{0.125}{1})^{1*8}$

$A=1,000(1.125)^{8}$

$A=\$2,565.78$
