If 75 people attend a concert and tickets for adults cost $2.75 while tickets for children cost $2.25 and

Serhud [2]

Answer:

Adult = 39

Children = 36

Step-by-step explanation:

The total number of people = 75

Cost of adult ticket = $2.75

Cost of children ticket = $2.25

Total receipts = $188.25

Let the number of adult = x

Let the number of children = y

X + y = 75 ......equation (i)

(X × 2.75) + (y × 2.25) = 188.25

2.75x + 2.25y = 188.25.......equation (ii)

To find the numbe of adult and children that attended, we'll have to solve equation (i) and (ii) simultaneously.

From equation 1,

X + y = 75

X = 75 - y......equation(iii)

Put equation (iii) into equation (ii)

2.75*(75 - y) + 2.25y = 188.25

206.25 - 2.75y + 2.25y = 188.25

206.25 - 0.5y = 188.25

Collect liketerms

0.5y = 206.25 - 188.25

0.5y = 18

Y = 18 / 0.5

Y = 36

Put y = 36 into equation (i)

X + 36 = 75

X = 39

Therefore the number of adult is 39 while that of children is 36.

Round your answer to two decimal places

Rounding a 10-meters long rope to form a circle will give you a circle whose circumference is 10 meters. In every circle, the following formula links radius and circumference together:

$C = 2\pi r \iff r = \dfrac{C}{2\pi}$

So, in your case, the radius will be

$r = \dfrac{10}{2\pi} = \dfrac{5}{\pi} \approx 1.591549\ldots$

which we can best approximate as 1.59
