Solve the proportion 40/z+1 = 15/6

vovangra [49]

Answer:

Step-by-step explanation:

$\frac{40}{z + 1} = \frac{15}{6} \\$

<u>Cross multiply </u>

That's

$15(z + 1) = 40(6) \\ 15z + 15 = 240$

<u>Send 15 to the right side of the equation</u>

$15z = 240 - 15 \\ 15z = 225$

Divide both sides by 15

$\frac{15z}{15} = \frac{225}{15} \\$

We have the final answer as

When his daughter alisa was born mike began saving for her wedding. He wanted to have saved about 30,000 by the end of 20 years

Gennadij [26K]

Answer:

$\$16,610.27$

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

$t=20\ years\\A=\$30,000\\ r=0.03\\n=1$

substitute in the formula above

$30,000=P(1+\frac{0.03}{1})^{1*20}$

$30,000=P(1.03)^{20}$

$P=30,000/(1.03)^{20}$

$P=\$16,610.27$
