(100 pts)

Answer 1

$\\ \sf\longmapsto Discount=\dfrac{12.5(30}{100}$

$\\ \sf\longmapsto Discount=12.5(0.3)$

$\\ \sf\longmapsto Discount=125(3)/100$

$\\ \sf\longmapsto Discount=375/100$

$\\ \sf\longmapsto Discount=3.75$

Answer 2

Answer:

discount = $3.75

Step-by-step explanation:

Given:

$\sf \dfrac{discount \times 100}{100}=\dfrac{\ 12.50 \times 30}{100}$

Multiply both sides by 100 to eliminate the denominators:

$\implies \sf discount \times 100=\ 12.50 \times 30$

Divide both sides by 10:

$\implies \sf discount \times 10=\ 12.50 \times 3$

Carry out the multiplication on the right side:

$\implies \sf discount \times 10=\ 37.50$

Divide both sides by 10:

$\implies \sf \dfrac{discount \times 10}{10}=\dfrac{\ 37.50}{10}$

$\implies \sf discount=\ 3.75$
