The third constraint was based on the total area that the
garden can only take. Now the last constraint must be based on the total cost
that should be spend in order to make a 500 square feet of garden, that is:
<span><u>4 </u>z + <u>3</u> p ≤ <u>600</u></span>
<span> w = ±√ 7.087 = ± 2.66207</span>
Answer:
a) Here x represent number of ride tickets
z represent admission fees. = $20
y represent total cost.
Step-by-step explanation:
a) Here x represent number of ride tickets
z represent admission fees.
y represent total cost.
b) Given that,
$0.75 per ticket for the rides.
Number of tickets (x) = 18
Total spent (y) = $33.50
Total cost = (number of tickets)*(price per ticket) + admission fees
y =0.75x + a
We can calculate the cost for anyone who only pays for festival admission and rides.
c)
Put y = 33.50
x = 18
33.50 = 0.75*18 + a
33.50 = 13.5 + a
Solve for a,
Subtract 13.50 both the side
33.50 - 13.50 = 13.50-13.50 + a
20 = a
So, admission cost (a) = $20
Answer:
x = -1.3
Step-by-step explanation:
5x +9=2.5
subtract 9 from both sides
5x = -6.6
divide both sides by 5
x=-1.3
Answer:
52 students
Step-by-step explanation:
Let's assume A represents number of students in the library means A=86,
B represents number of student in student union means B = 78
U represents total students surveyed means U = 136
section II represents number of students in library and student union means
II = 34
Now from figure we can see
number of students only in library is represented by section I .
and section I can be written as
I = A - II
I = 86-34 = 52
only in Union represents III
III = B - II
III = 78-34 = 44
not in library or not in union = U - (I + II + III)
= 136 - (52+ 34+ 44)
= 136 - 130 = 6
