Step-by-step explanation:
Answer:
0.12 = 12%
Step-by-step explanation:
To find this probability, we need to multiply the probability of getting route B, and the probability of getting home by 4 P.M if we choose route B.
If the probability of choosing route A is 60%, we have that the probability of choosing route B is 100% - 60% = 40%
Then, we have that the probability of getting home by 4 P.M. when choosing route B is 30%, so the final probability is:
P = 40% * 30% = 0.4 * 0.3 = 0.12 = 12%
Answer:
$18
Step-by-step explanation:
Let's subtract the lunch from the trip total to get the remainding cost!
36.50 - 9.50 = $27
Now let's set up an equation to figure out the amount of the entrance ticket and the gift coupon!
let's have x = the entrance ticket
27 = x + 1/2(x) -----------> 1/2 is next to x, because the gift coupon is 1/2, or 50% of the entrance ticket! Now solve for x!
27 = 3/2x
(2/3) 27 = 3/2x (2/3)
18 = x, so the entrance ticket is $18!
