Answer: fries=$3.20, burgers=$5.79

Step-by-step explanation:

  1. form equations for each person
  2. set them up one below the other
  3. solve for one unknown
  4. plug in that answer into one of the equations to get the other unknown

(f=fries, b=burger)

21.18=2b+3f

29.56=4b+2f

-2(21.18=2b+3f)

 29.56=4b+2f  

-42.36=-4b-6f

<u>29.56=4b+2f</u>

  -12.8=-4f

    3.2=f

21.18=2b+3(3.2)

21.18=2b+9.6

-9.6         -9.6

11.58=2b

 5.79=b

Find f(g(x)) f(x)=2x-5 , g(x)=4x+3
hichkok12 [17]

Set the composite results function.

\boldsymbol{f(g(x)) }

Evaluate f(g(x)) by substituting the value of g into f.

\boldsymbol{2(4x+3)-5}

Simplify each term.

Apply the distributive property.

  • \boldsymbol{f(4x+3)=2(4x)+2\cdot3-5 }

Multiply 4 by 2.

  • \boldsymbol{f(4x+3)=8x+2\cdot3-5 }

Multiply 2 by 3.

  • \boldsymbol{f(4x+3)=8x+6-5 }

Subtract 5 from 6.

  • \boldsymbol{f(4x+3)=8x+1 }

\red{\boxed{\green{\boxed{\boldsymbol{\purple{Pisces04}}}}}}

$30 board game on sale for $20.10

Ok so to solve for percent off
percent off means discount


so therefor we need to find how much was discounted
30-20.10=9.90

so we see that 9.90 was discounted
to find the percent we do
discount/total=percent discount
9.90/30=0.33

percent means parts out of 100
0.33/1 times 100/100=33/100=33%

answer is 33% discout
