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.

Answer:

\large\boxed{2a+14}

Step-by-step explanation:

4(a + 2 ) - 2 (a - 3)\qquad\text{use distributive property:}\ a(b+c)=ab+ac\\\\=4a+8-2a-(-6)\qquad\text{combine like terms}\\\\=(4a-2a)+(8+6)\\\\=2a+14

Solve the system of equations using the substitution method. 2x+8y=4 x=−3y+5
goldenfox [79]
Since x=-3y+5, substitute x for -3y+5. 

2(-3y+5)+8y=4

Distribute. 

-6y+10+8y= 4

2y+10= 4

Subtract 10 on both sides. 

2y=-6

Divide by 2.

y=-3

Plug in y=-3. 

x=-3(-3)+5
x= 9+5
x=14

(14,-3)

We can check this. 

2(14)+8(-3)=4
28-24=4
4=4 <== this works

I hope this helps!
