Answer:
P = 0.23375
Step-by-step explanation:
given,
you remain in store for 15 minutes.
you friend remains in store for 10 minutes.
probability that they are store at the same time
from the graph attached below
shaded region shows the required probability,.
probability of the square = 1
probability of the shaded region = 1 - (area of lower triangle - area of upper triangle)
area of lower triangle = \dfrac{1}{2}(0.85)(0.85)
= 0.36125
area of the upper triangle = \dfrac{1}{2}(0.9)(0.9)
= 0.405
probability of the shaded region = 1 - (0.36125+0.405)
= 0.23375
Answer:
$180
Step-by-step explanation:
Since the cost of the telescope with the 30% discount is $126 then $126 is 70% of the original price. Remember 100-30=70. To find the original price set up a proportion with these values:

Solve for the original price by cross multiplying numerator with denominator.
x(70) = 126(100)
70x = 12600
x= $180
