Answer:
a)£21.80
b) 3 trips
Step-by-step explanation:
The cost of an adult is $10.
A child’s ticket is $6.
FAMILY DISCOUNT CARD
- 45% off all adults tickets
- Children save 2/5 off of full price tickets
a) How much will it cost to buy 2 adult tickets and children’s tickets?
(a)
Adults: 2 × £10 = £20
(45 ÷ 100) x £20 = £9
£20 - £9 = £11
Children: 3 × £6 = £18
2
/5
of £18 = £7.20
£18 - £7.20 = £10.80
Total: £11 + £10.80 = £21.80
b) The cost of a family discount card is $40 per year. How many times in the same year would 2 adults and 3 children need to go before you start to savemoney on the cost of the card?
(b) Cost without discount = £20 + £18 = £38b)
No card
1 trip
1 × £38 = £38
2 × £38 = £76
3 × £ 38 = £114
With card
£40 + (1 × £21.80) = £61.80
2 trips 2 × £38 = £76 £40 + (2 × £21.80) = £83.60
3 trips 3 x £38 = £114 £40 + (3 × £21.80) = £105.40
3 trips before the discount card starts being cheaper than regular price
The limit as x approaches three from the right of f(x) is 3
<h3>What is the Limit of a function ?</h3>
The value a function approaches when the variable approaches its limit.
A graph is given which shows a piece wise function ,
As when the limit approaches from the right the function can be seen approaching 3 , it is not 3 at 3 but approaching to 3
The right hand lim x--> 3 f(x) approaches 3 .
Therefore , limit as x approaches three from the right of f(x) is 3

Here is the graphed part. Hope this helped!
The y - intercept of given equation is (0, 5)
<em><u>Solution:</u></em>
Given that we have to find y - intercept of the given equation
<em><u>Given equation is:</u></em>
The y-intercept is the point at which the line crosses the y-axis. At this point, the x-coordinate is zero
<em><u>Finding y - intercept:
</u></em>
To find the y-intercept, plug 0 in for 'x' and solve for 'y'
Substitute x = 0 in given equation
Thus the y - intercept of given equation is (0, 5)
