Nikkis charges are 20,40,50,80. Dave’s charges are 25 and 37.5.
1/16=1,003, so
senior= 1003
infants=3009
children=6018
adults=6018
Answer:
6.25 litres
Step-by-step explanation:
ratio 1:4
25/4 = 6.25
4 * 6.25 = 25
1 * 6.25 = 6.25
= 6.25 litres of concentrate
39) y=20x+175
40) y=20(2)+175, so $215
At sea level, the pressure is 1013, that's when the altitude is at 0, sea level, let's see

so, the inital amount is 1013, when t = 0,

now, to check the atmospheric pressure at 4000, simply set t = 4000, to get A.
