Answer:

180%

Step-by-step explanation:

Set up an equation:

Variable x = percent of markup

102.56/56.98 = x/100

Cross multiply

102.56 × 100 = 56.98 × x

10,256 = 56.98x

Divide both sides by 56.98:

179.99297.... = x

Round to nearest whole number:

180 = x

Check your work:

56.98 × 180%

Convert the percentage into a decimal:

56.98 × 1.80

102.564

Round to nearest cent:

102.56

Correct!

Mashutka [201]

Answer:

Students liked to play football are 210 .

Step-by-step explanation:

Formlua

$Percentage = \frac{Part\ value\times 100}{Total\ value}$

As given

In a school, 42% of the students liked to play football and 24% liked to play tennis.

As the percentage is always 100% .

Percentage of students choose swimming = ( 100 - 42 - 24) %

= (100 - 66) %

= 34 %

The rest of the students choose swimming If 170 students choose swimming .

Part value = 170

Percentage = 34 %

Putting all the values in the formula

$34 = \frac{170\times 100}{Total\ value}$

$Total\ value = \frac{17000}{34}$

Total value = 500

As the percentage for students liked to play football = 42%

Putting in the formula

$42 = \frac{Part\ value\times 100}{500}$

$Part\ value= \frac{42\times 500}{100}$

$Part\ value= \frac{21000}{100}$

Part value = 210

Thus

Students liked to play football = 210

Therefore the students liked to play football are 210 .
