Part 2: If each CD cost $14.25, solve the equation to find the cost of each DVD. Show your work.

Answers

Answer:gchckc

Step-by-step explanation:

let x be CDs and y be DVDs
2x + 5y = 138.45
plug in the cost of the CDs for x
2(14.25) + 5y = 138.45
multiply
28.50 + 5y = 138.45
subtract 28.50 from both sides to isolate y
5y = 109.95
divide both sides by 5 to isolate y
y = 21.99

Step-by-step explanation:

Answer:

x= 72.72 (with a line over it)

Step-by-step explanation:

(x - 5) + (1.4x) + (x) + (x + 35) = 360

Step 1. Simplify both sides of the equation.

x + 5 + 1.4x + x + x + 36 = 360

(x + 1.4x + x + x) + (5 + 35) = 360 (combine like terms)

4.4x + 40 = 360

Step 2. Subtract 40 from both sides.

(4.4x + 40) - 40 = (360) - 40

4.4x = 320

Step 3. Divide both sides by 4.4

4.4x/4.4 = 320/4.4

x = 72.72 (72 repeats, so 72 with a line over it)

The table below shows prices for breakfast items at a food truck. Jeffrey ordered 2 breakfast tacos with bacon, an order of potato hash and a cup of coffee. The sales tax for the order was $0.75. He paid for his breakfast with a $10 bill. Breakfast Menu Item Price 1 Breakfast taco - egg & cheese $2.00 1 Breakfast taco - with bacon $2.25 1 Order of potato hash $1.50 Cup of coffee $0.50 How much change should Jeffrey receive from a $10 bill? O A $2.75 O B. $6.50 OC. $8.50 OD. $4.25​

Answers

Answer: A.$2.75

Equation: 2(2.25)+1.50+0.50+0.75

Because he bought 2 breakfast tacos with bacon and the price of that is $2.25 for 1 then he bought a potato hash for $1.50 and a cup of coffee for $0.50 and the tax is $0.75

Answer: 2.75. In change

Step-by-step explanation:

First add the two breakfast tacos, since one is 2.25$ Two would be 4.50$ Next add the potato hash and cup of coffee, you should get 2.00$ After that add the tacos with the coffee and potato hash which equals 6.50$ and don't forget to add your 0.75. Tax to the 6.50$ once you get 7.25. You need to do 7.25. - 10.00 which would get you your change of 2.75$
