Answer:
b=5-x
Step-by-step explanation:
2(x+b)=10
Divide both sides by 2.
x+b=5.
Subtract x.
b-5-x.

First figure out Info needed
So 142 people 6 drivers
2 vehicles of which are bus and vans
Van:capacity of 10 Bus:capacity of 51
So plug in x for buses and y for vans
x+y+6=142
Subtract 6
x+y=136
51 times 2 gives you 102 for the bus capacity so two buses
x(2)+y=136
51(2)+y=136
102+y=136
Subtract 102
Giving you 34
y=34
4 vans because
34 divided by 10 is 3.4 but there is no 3.4 van so round up to 4
You end up needing 2 buses and 4 vans
Answer:
x = 57.2 ft
Step-by-step explanation:
cos 5° = 57/x
0.9962 = 57/x
x = 57.2 ft
a. Let us say that c(x) is the cost of one t shirt based
on the number of increases therefore:
c = 10 + x
b. Say that t(x) is the number of t shirts sold based on
the number of increases so:
t = 2500 – 100 x
b. The revenue is simply the product:
r(x) = (10 + x) (2500 – 100 x)
Combining:
r(x) = 25000 – 1000 x + 2500 x – 100 x^2
r(x) = 25000 + 1500 x – 100 x^2
Taking the 1st derivative and setting dr / dx
= 0 to get the maxima:
dr / dx = 1500 – 200 x
1500 = 200 x
x = 7.5
t = 2500 – 100 x = 2500 – 100 (7.5) = 1750
Hence 1750 shirts should be sold.
