<span>If the tip, t, varies directly with the number of guests, g, then it means that any change in tip there is a corresponding change in the number of guests. When the tip increases the number of guests increases as well. Therefore,

t </span>α g

To change the it to equal sign, we incorporate a proportionality constant, k.

t =<span> kg
</span>
This equation will represent the relation of t to g

Answer:

35 students

Step-by-step explanation:

Find 25% of 500:

$\frac{25}{100}$ × $\frac{500}{1} = \frac{12500}{100}$
$\frac{12500}{100} = \frac{125}{1} = 125$

Find 18% of 500:

$\frac{18}{100}$ × $\frac{500}{1} = \frac{9000}{100}$
$\frac{9000}{100} = \frac{90}{1} = 90$

Find the difference:

125 - 90 = 35

So, 35 more students prefer video games to bike riding.

I hope this helps!

If the interest rate is 7%, how many years will it take for your bank balance to double from $1,000 to $2,000?Enter the followin

svlad2 [7]

Answer:

It will take 14.29 years for your bank balance to double from $1,000 to $2,000.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

$T = E + P$ .

If the interest rate is 7%, how many years will it take for your bank balance to double from $1,000 to $2,000?

We have that $P = 1000, I = 0.07$

We want to find t when E = 1000, so $T = P + E = 2000$ .

$E = P*I*t$

$1000 = 1000*0.07*t$

$t = \frac{1}{0.07}$

$t = 14.29$

It will take 14.29 years for your bank balance to double from $1,000 to $2,000.

Answer:

9/4

Step-by-step explanation:

2(x - 10) + 4 = -6x + 2

2x - 20 + 4 = -6x + 2

2x - 16 = -6x + 2

8x - 16 = 2

8x = 18

x = 18/8 or 9/4

Debra plans to invest $2,250 for 10 years. She can invest in a savings account that pays 4% simple intrest or a savings account

Diano4ka-milaya [45]

Answer:

$\$180.55$

Step-by-step explanation:

step 1

<u><em>Simple interest</em></u>

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=10\ years\\ P=\$2,250\\r=4\%=4/100=0.04$

substitute in the formula above

$A=2,250(1+0.04*10)$

$A=2,250(1.4)$

$A=\$3,150$

step 2

<u><em>Interest compounded annually</em></u>

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

$t=10\ years\\ P=\$2,250\\r=4\%=4/100=0.04\\n=1$

substitute in the formula above

$A=2,250(1+\frac{0.04}{1})^{1*10}$

$A=2,250(1.04)^{10}$

$A=\$3,330.55$

step 3

Find the differences between the two final amounts

$A=\$3,330.55-\$3,150=\$180.55$
