Isabella invested $1300 in an account that pays 4.5% compounded annually. Assuming no deposits or withdrawals are made , find ho

Anastaziya [24]

Answer:

$2,407.5

Step-by-step explanation:

To solve this question, we will use the formula for calculating the amount formula as shown;

A =P(1+r)^n

Given that;

P = #$1300

r = 4.5% = 0.045

t = 14years

Substitute

A = 1300(1+0.045)^14

A = 1300(1.045)^14

A = 1300(1.8519)

A = 2,407.5

Hence Isabella would have $2,407.5 in her account after 14years

CAN SOMEONE HELP PLZ

Vlad1618 [11]

Answer:

Step-by-step explanation:

The solution to the system (c , p) represent the cost of each hot cocoa is c and the cost of each pretzel is p

Nothing changed just two equations were added to form another third equation which represent the total cost of 7 cups of hot cocoa and 8 pretzels

so the solution (c , p) would still be the same as the solution represents cost of each cup of hot cocoa c and cost of each pretzel p

No adding both the equations does not help us solve the equation, It just forms another equation further making the question longer and the third equation is not needed because to solve a system of equations with 2 variables to equations are enough, in this case c and p To solve the system of equations we multiply the first equation with 2 and the second equation with 5 and then subtract equation 1 from equation 2

$Equation\ 1 \\\\5c+4p=18.40\\Multiplying\ it\ with\ 2\\10c+8p=36.8\\\\Equation\ 2\\\\2c+4p=11.20\\Multiplying\ equation\ 2\ with\ 5\\10c+20p=56\\\\Now\ subtract\ equation\ 2\ from\ equation\ 1\\\\10c-10c+8p-20p=36.8-56\\0-12p=-19.2\\-12p=-19.2\\p=-19.2/-12\\p=1.6\\$

Now for the value of c we insert the value of p in any equation, lets insert it in equation 1

$5c+4p=18.40\\5c+4(1.6)=18.40\\5c+6.4=18.40\\5c=12\\c=12/5\\c=2.4$

A hospital has been vaccinating people in two different locations. At the start of the month, location A has reported it has vac

Flauer [41]

Since Location A has vaccinated 10 thousand people at the start of the month, then write 10 on the first row of the first colum.

Since they can apply vaccines at a rate of 20 thousand people per week, add 20 thousand to the value on each row (in thousand) to find the value of the next. Then, the column A will contain the following data:

0: 10

1: 30

2: 50

3: 70

4: 90

5: 110

6: 130

Similarly, place 60 thousand on the first row on the column B and ad 5 thousand each time:

0: 60

1: 65

2: 70

3: 75

4: 80

5: 85

6: 90

Don't forget to show the calculations on the answer. For column A:

10+20=30

30+20=50

... and so on.

For column B, start with 60 and add 5 each time.
