Please help I don't know this and it's due today <br><br>5 - x = 12
attashe74 [19]
5 - x = 12

We're essentially just trying to get "x" onto its own side.

So, simply subtract 5 from both sides.

-x = 12 - 5

Simplify.

-x = 7

Now, divide both sides by -1.

x = -7

Fred buys flags from a manufacturer for f dollars each and then sells the flags in his store for a 26%markup.
Mashutka [201]

Answer:

the markup is 1.26 (the amount added is .26)

1.26x (when x is the price Fred buys them for from the manufacturer)

1.26(40)

$50.40 is the retail price

50.4-40

$10.40 is the markup

Step-by-step explanation:

The 26% markup means that he is selling the flags 26% above the cost.

So, the cost would represent 100%, which is 1, and 26% of markup in decimal number is 0.26.

The price including the markup would be 1.26 as decimal or 126% as percentage.

The problem states that the cost is unknown, so we represent that with a variable x. The retail price would be 1.26x, which is 126% per flag.

Finally, if Fred paid $40 per flag, the actual retail price would be:

1.26($40)=$50.40.

With $10.40 of markup.
