Answer:

Step-by-step explanation:

1/25 is the same thing as $5^{-2}$ . So, u wantn to find whcih answer choice does not equal that. You can use the exponent multiplication rule, where x^a times x^b equals x^a+b.

for example, answer choice A would be 5^(3+-5) which is 5^-2.

the only choice that does not equal 5^-2 is D because it equals 5^2

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.
