20 students are going to the trip and of those 20, 10 are bringing their own lunches
Answer:
$63.60
Step-by-step explanation:
After the 25% markup, the price is ...
$60 + 0.25·60 = $75
After the 20% discount, the price (before tax) is ...
$75 - 0.20·75 = $60
After tax is added, the price is ...
$60 + 0.06·60 = $63.60
_____
Effectively, the original price is multiplied by ...
(1.25)·(0.80)·(1.06) = 1.06
The resulting price with tax is ...
1.06·$60 = $63.60
X would be the number of years between 1920 and 1980:
1980-1920 = 60 years.
Replace x with 60 and solve:
Y = 0.34(60) + 44.63
Y = 20.4 + 44.63
Y = 65.03
Answer: 65.03 meters
