Find the percent of the number. 30% of 30 is Explain your method.

nirvana33 [79]

Answer:

The answer would be 9

Step-by-step explanation:

Step 1: Our output value is 30.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$30=100\%$.

Step 4: Similarly, $x=30\%$.

Step 5: This results in a pair of simple equations:

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

Step 7: Again, the reciprocal of both sides gives

Therefore, 30% of 30 is 9

1. A family eats at a restaurant. The bill is $42. They have a coupon that gives them 15% off

Ludmilka [50]

<h2>a.</h2><h3>Solution:</h3>

$42 - 42 \times 15\%$

$=42 - 42 \times \frac{15}{100}$

$=42 - 21 \times \frac{15}{50}$

$=42 - \frac{315}{50}$

$= 42 - 6 \: \frac{15}{50}$

$= 41 \: \frac{50}{50} - 6 \: \frac{15}{50}$

$= 35 \: \frac{35}{50}$

$= 35.70$

<h3>Answer:</h3>

The family did spend $35.70 on the meal after the coupon

<h2>b.</h2><h3>Solution:</h3>

$35.70 + 42 \times 20\%$

$= 35.70 + 42 \times 0.2$

$= 35.70 + 8.4$

$= 44.10$

<h3>Answer:</h3>

The family did spend $44.10 on the meal in total.
