Answer:
Number of child tickets = 800
Number of adult tickets = 330
Step-by-step explanation:
Let c = number of child tickets
and a= the number of adult tickets.
We are given:
The admission fee at the steamboat springs hot air balloon festival is $1.50 for children and $4.00 for adults.
On a certain day, 1,130 enter the festival and 2, 520 is collected.
Making equations:
(because total people entered are 1130, so adding number of adult and child tickets will give us total number of people)
(because total money collected is 2520, so adding coat of adult and child tickets will give us total money)
Now, solving these equations simultaneously, we can find values of x and y
Let:
From equation 1 find value of c and put it in eq(2)
Putting value of c in eq(2)
So, we get value of a = 330
Now, punting value of a in eq(1) to get value of c
So, we get value of c = 800
Therefore:
Number of child tickets = c= 800
Number of adult tickets = a = 330
Answer:
Total cost to paint the room = £73.51
Step-by-step explanation:
Given:
Dimensions of the room = 6.8 m 9.2 m
Cost of tin of paint = £11.75
A tin of paint covers an area = 20
To find the cost of painting the room with two coats of paint.
Solution:
Area of the room =
We will use unitary method to find the amount of paint required for the room.
If of area is covered by 1 tin of paint.
For of area, amount of paint required =
of a tin
Then, for amount of paint required =
tins of paint.
<em>For double coats twice paint must be required.</em>
So, total amount of paint required for painting the room with two coats of paint = tins of paints.
Using unitary method to find total cost.
If 1 tin of paint costs = £11.75
<em>6.256 tins of paint will cost = </em>
Total cost to paint the room = £73.51
