Answer:
(20-C)15+10C=225
Step-by-step explanation:
20 TICKETS
Adults = (20 - the number of children) x $12
(20-C)15+10C=225
300 - 15C + 10C = $225
300 - 5C = 225
-5C = -75
C= 15
A = 5
Children 15 x $10 = $150
Adults 5 x $15 = $75
$150 + $75 = $225
Answer:
Both = 0.3025 or 30.25%
At least one = 0.7975 or 79.75%
Step-by-step explanation:
The probability that one of the two is allergic to pollen is 55% so the probability that both are allergic is given by:
The probability of at least one of them being allergic can be given by the whole minus the probability of neither being allergic:
Answer:
(a) d = 4t
(b) d = 2.5t
(c) 45 = 2.5(x) x = 18
(d) d = 4(80) d = 320
(e) If Kyle walks 4 feet per second, then after 7 seconds he will walk 28 feet. 28 = 4(7)
