HURRY PLEASE HELP Missy borrowed $5900 for seven years at an annual rate of 8%. What is the TOTAL AMOUNT that Missy will need to pay after 7 years? (principal AND interest)

Answers

Answer: $5933.04

Step-by-step explanation:

Principal = $5900

Rate = 8%

Time = 7 years

Simple interest = PRT/100

= (5900 × 8% × 7)/100

= (5900 × 0.08 × 7) / 100

= 3304/100

= $33.04

Total amount = Principal + Interest

= $5900 + $33.04

= $5933.04

mr cadwell wants to purchase a motorcycle. he has financing options a and b to chose from, as shown below.
Option A-
Down Payment: $1,000
Monthly payment for 3 years: $85

Option B-
Down payment: $1,200
Monthly Payment for 3 years: $85

The purchase of the motorcycle is $3,500, including tax. Based on the info provided in the table, which statement is true?

Option B is better
Option A is better

Answers

Answer:

Option A is better.

Step-by-step explanation:

We will observe both plans one by one to determine which one is better i.e. which one will has less interest to pay.

So,

Option A:

Down Payment: $1,000

Monthly payment for 3 years: $85

The total amount in installments will be:

[tex]=Amount\ per\ month * months\\= 85*36\\=3060[/tex]

The total price of bike will be:

[tex]Total\ price = Downpayment +Installments\\= 1000+3060\\= 4060\\Interest = Total\ price - Purchase \\= 4060-3500\\=560[/tex]

Option B:

Down Payment: $1,200

Monthly payment for 3 years: $85

The total amount in installments will be:

[tex]=Amount\ per\ month * months\\= 85*36\\=3060[/tex]

The total price of bike will be:

[tex]Total\ price = Downpayment +Installments\\= 1200+3060\\= 4260\\Interest = Total\ price - Purchase \\= 4260-3500\\=760[/tex]

We can see that interest in Option A is less than interest in Option B that means Mr. Cardwell will have to pay less amount in Option A.

Hence,

Option A is better.

Kenzie is putting the family vacation videos onto a flash drive. The flash drive can hold 200 minutes of video. Kenzie has used 45% of the memory space already. How many minutes of the flash drive has she already used?

Answers

Answer:

90 minutes

Step-by-step explanation:

In order to calculate a percentage of the minutes of video we simply need to divide the percentage by 100 and then multiply that value by the total number of minutes that the flash drive can hold. Since we are given this total number of minutes then we can simply plug it in and solve for x which represents the percentage of memory used in minutes.

x = 200 * (45 / 100)

x = 200 * 0.45

x = 90 minutes

Therefore, Kenzie has already used 90 minutes of video on the flash drive.

Answers

Answer:

Option A

Step-by-step explanation:

to be perpendicular, the product of two slopes should be -1

the slope of the first equation is 1/5, so the slope should be -5

(1/5) (-5)= -1

y= -5x +b

Substitute (1,1) to solve for b,

b= 6

Thus, the equation is y= -5x +6

This morning, Mai's car had 15.25 gallons of fuel. Now, 1.9 gallons are left. How much fuel did Mai use?

Answers

Answer:

13.35

Step-by-step explanation:

Just subtract. 15.25-1.9 gives you the difference.

Mai used 13.35 gallons of fuel.

Unitary method is a process by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.

To calculate the fuel Mai used, we can subtract the remaining fuel from the initial amount of fuel.

This can be done as follows:

Initial amount of fuel = 15.25 gallons

Remaining amount of fuel = 1.9 gallons

Fuel used = Initial amount of fuel - Remaining amount of fuel

Therefore, Fuel used = 15.25 - 1.9

Fuel used = 13.35

Therefore, We can conclude that Mai used 13.35 gallons of fuel.
