Answer:
Option A
a + s = 1650 ; 3.5a + 2b = 4580
Step-by-step explanation:
a ------> number of adult tickets
s ------> number of student tickets
Total tickets = $ 1650
a +s = 1650
Cost of 'a' number of adult tickets = 3.50*a = 3.5a
Cost of 's' number of student tickets = 2*s = 2b
Revenue raise = $ 4580
3.5a + 2b = 4580
Answer:
last answer is correct...
1. Interval estimate
2. Point estimate
3. Sample data
4. Probability
Answer:
75%=x-125
90%=x+250
subtract the second from the first
15%=375
100%=?
100%×375/15
100%=2500marked price is 2500
2500+250=2750
90%=2750
100%=?
cost price=3055.56
Answer:
18 points
Step-by-step explanation:
We first need to find the percent increase for both Iliana an Fiona.
To do so, we take the absolute value of difference (the score increase) and we compare/divide it by the original score they had.
So, for Iliana, we have a starting score of 65 and an increase of 21 (86-65).
Her percent of increase is 21/65 = 32.3%
For Fiona, she went from 70 and had a 10 points increase (80-70).
Her percent of increase is 10/70 = 14.3%
The difference between the two percent of increase is 18 points (32.3 - 14.3)
