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.
the length of z is C. 15 cm
Keeping in mind that, there are 5280 feet in 1 mile and 60 minutes in 1 hour.
16 out of a number is equal to 8 find that number.
SOLUTION
representing the unknown value by C,
I think C= 2
because 16/C=8
making C the subject, Multiply both sides by C and divide bother sides by 8.
I hope this helps
Answer:
Domain = 0≤m≤20 for mEZ+
Range = $100≤A≤$700 for all values of m
Step-by-step explanation:
Initial amount in the account = $100
Amount saved by beth monthly = $30
Amount in the bank after X month = $100+$30X where X is the number of months beth intend to save up to.
The amount in her bank in her first month = $100+$30(1)
= $100+$30
= $130
Amount saved in the second month will be when X = 2
= $100+$30(2)
= $100+$60
= $160
The amount in the bank will keep increasing by $30 monthly until the 20month.
The amount he will have in her bank in the 20th month will be at when X = 20
= $100+30X
= $100+30(20)
= $100+$600
= $700
This means that her money will be $130 in the first month and will keep increasing until it reaches $700 in the 20th month.
The DOMAIN will be the interval of the time she used in saving. Since she saved for 20months, the domain will be expressed as 0≤m≤20 for mEZ+ where m is the number of month she uses to save.
The Range will represent the amount she saved within the specified time and will be expressed as $100≤A≤$700 for all values of m.
Where $100 is the amount in the account initially and $700 is the amount in the account after 20 months.
