Earl invested 6,000 in a money market account that pays 5% interest quarterly. How much money will he have in his account after
Sedbober [7]

Answer:

The amount becomes $6964.53 after 3 years .

Step-by-step explanation:

Formula

Amount = P (1+\frac{r}{4})^{4t}

Where P is the principle , r is the rate of interest in the decimal form and t is the time in the years .

As given

Earl invested 6,000 in a money market account that pays 5% interest quarterly for 3 years .

P = $6000

5% is written in the decimal form.

= \frac{5}{100}

= 0.05

r = 0.05

t = 3 years

Putting all the values in the formula

Amount = 6000(1+\frac{0.05}{4})^{4\times 3}

Amount = 6000(1+0.0125)^{12}

Amount = 6000\times 1.16075452

Amount =\$ 6964.53\ (Approx)

Therefore the amount becomes $6964.53 after 3 years .

The average weekly salary of two employees is $5250. One makes $500 more than the other. Find their salaries.
irga5000 [103]

Answer: thier salaries are $5000 and $5500

Step-by-step explanation:

Let the average weekly salary of one employee be =x

And that of the other employee be = x+500

Such that if thier average of their salaries= $5250

So, their total salary=  $5250 x 2=10,500

The  equation  to solve each employee salary becomes

x+x+500=10,500

2x+500=10,500

2x=10,500-500

2x=10,000

x=10,000 /2

x= first employee salary =$5000

second employee =   x+500 =$5500
