Answer:
value of gold is $33.17
Step-by-step explanation:
given data
depth d = 3800 m = 3.8 km
area A = 3.63 × 10^8 km²
average concentration = 5.8 × 10^−9 g/L
price of gold = $129.00 / troy oz
to find out
value of gold
solution
first we find volume that is
volume v = A× d
put here value
volume = 3.8 × 3.63 × 10^8
volume = 13.794 × km³
volume = 137.94 × L
so mass = 5.8 × × 137.94 ×
mass = 8 × g
mass = 0.2572 troy oz
here we know 1 troy oz = 31.1 g
and we know 1 troy oz = $129
so 0.2572 troy oz = 129 × 0.2572
0.2572 troy oz value is $33.17
value of gold is $33.17
Answer:
170
Step-by-step explanation:
The bus company charges $120 for each passenger up to 100. They charge $0.50 less per person over 100. This means for 101 passengers they charge $119.50, for 102 passengers they charge $119 etc. The total revenue for the bus company will be the price of each ticket times the number of passengers. This is shown below in the table.
Passengers Revenue
100 100*120 = 12000
101 101*119.50 = 12069.5
102 102*119 = 12138
103 103*118.50 = 12205.5
104 104*118 = 12272
105 105*117.50 = 12337.5
....
150 150*95 = 14250
....
170 170*85 = 14450
....
175 175* 82.5= 14437.5
The max revenue the company receives is 170 passengers.
