Dollars
-----------
Students
Dollars: 95 x
--------------------- = ------
Students: 20 162
Cross multiply: 95(162) = 20x
15,390 = 20x
----------------------
20 20
769.5 = x
Therefore, it will cost $769.50 for 162 students to visit an aquarium.
Answer:
$14,080
Step-by-step explanation:
You can use a formula for exponential decay, but since it is only 2 years, you can find 80% of the original value, and then 80% of the new value.
Original value: $22,000
Value after 1 year: 80% of $22,000 = 0.8 * $22,000 = $17,600
Value after 1 year: $17,600
Value after 2 years: 80% of $17,600 = 0.8 * $17,600 = $14,080
Answer: $14,080
