Answer:

Step-by-step explanation:

S=student cost; T=teacher cost

32S+3T=$127 . Multiply this by 2.

64S+6T=$254 Subtract this below

25S+2T=$97.50 . Multiply this by 3.

75S+6T=$292.50

64S+6T=$254 . Subtract this (from above.)

11S=$38.50

S=$3.50

ANSWER 1: Student tickets cost $3.50.

32S+3T=$127

32($3.50)+3T=$127

$112+3T=$127

3T=$15

T=$5.00

ANSWER 2: Teacher tickets cost $5.00.

CHECK:

25S+2T=$97.50

25($3.50)+2($5.00)=$97.50

$87.50+$10.00=$97.50

$97.50=$97.50

Degger [83]

One may note the country's name is not finline or Finley, is Finland.

so, in short, if we take 137 to be the 100%, how much is 18.036 in percentage off of it?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
137&100\\
18.036&x
\end{array}\implies \cfrac{137}{18.036}=\cfrac{100}{x}\implies x=\cfrac{18.036\cdot 100}{137}$
