Step-by-step explanation:

Harpreet gave her car for service at the service station and was charged as follows: a) 3.1 litres engine oil at the rate of rupees 210 per litre and VAT 20%. b) rupees 1105 for all other services and VAT 12.5%. c) rupees 1600 as labour charges and service tax 10%. find the bill amount.​

Answers

Answer:Bill amount = 3,784.325 rupees.

Step-by-step explanation:

Calculating each service charge rendered to Harpreet, we have

a) 3.1 litres engine oil at the rate of rupees 210 per litre and VAT 20%

= 3.1 L X 210 rupees=651 rupees

VAT 20 % = 651 X 20%=130.2 Rupees

Charge on purchase of engine oil = 651 rupees + 130 .2 rupees=781.2 rupees

b) All other services = 1105

VAT 12.5% = 1105 X 12.5 %=138.125 Rupees

Charge on all other services = 1,105+ 138.125 rupees=1,243.125 rupees.

c.Labour charges = 1600

Service tax 10% = 1600 x10%=160

Charge on Labour = 1600+160=1760 rupees.

Bill amount = Total Charge on all services rendered at the station =781.2 rupees + 1,243.125 rupees + 1760 rupees= 3,784.325 rupees.


Jayla is a salesperson. She sold a guitar for $96 and earned 20% commission. How much
commission did jayla earn

Answers

Answer:

$115.20

Step-by-step explanation:

Hi! We need to find 1% of 96 to multiply by 20.

96 / 100 = .96

Now we multiply by 20.

20 x .96 = 19.2.

Now, we add 19.2 to what she earned in the first place (96).

19.2 + 96 = 115.20

A chef bought has $25 to buy ribs (x pounds) and chicken (y pounds). Ribs cost $2.00 per pound and chicken costs $1.50 per pound. Write an equation that represents the total amount of money spent on the ribs and chicken

Answers

Answer is 2x + 1.5y = 25

—
Total money spent is $25

Ribs weigh x pounds and costs $2 per pound

So we can write it as 2x

Chicken weighs y pound and costs $1.5 per pound

So we can write it as 1.5y

The equation can be written as:

2x + 1.5y = 25

Solve the system by substitution.
y=-x
-2x+5y=-28

Answers

Answer:

(4,-4)

x=4

y= -4

Step-by-step explanation:

We know that y is equal to and so we can plug the y value in for x into the other equation

-2x+5(-x)= -28

Solve for x

-2x-5x= -28

-7x= -28

x=4

Now that we know that x= -4 we can plug this into one of the two starting equations and solve for y

y= -(4)

y= -4

This is how I solved it !! Hope it helped , if you got any question about any step please let me know ;)
