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.

There are 100 seniors and 80 juniors in the Homecoming Parade. The students split up into groups of equal size, to fit on the pa

Masteriza [31]

Answer:

20 students should be on each float

Step-by-step explanation:

Number of seniors = 100

Number of juniors = 80

To find number of students that should be on each float, find highest common factor (H.C.F) of 100 and 80

Write prime factorisation of 100 and 80.

100 = $2^2$ × $5^2$

80 = $2^4$ × 5

So,

H.C.F(100, 80) = $2^2$ × 5 = 4 × 5 = 20

Therefore,

20 students should be on each float
