Let, the original amount = x
First discount = x * 0.20 = 0.20x
Amount after first discount = x - 0.20x = 0.80x
Second discount = 0.80x * 0.15 = 0.12x
Amount after second discount = 0.80x - 0.12x = 0.68x
Difference would be: x-0.68x = 0.32x
So, Your Answer would be 32%
Hope this helps!
70 = 4x
x equals the number of movies
divide both sides by 4
70 / 4 = x
17 .5 = x
Anderson will be able to go to 17 movies
Answer:
Option 4: 0.554
Step-by-step explanation:
As we can see that the intervals and their frequencies are given.
We have to calculate the probability of students' score falling between 70 and 89. It will use the frequency of both intervals 70-79 and 80-89.
So, combined scores of both intervals are:
172+105 = 277
Now to find the probability
= 277/500
=0.554
So option no 4 is the correct answer ..
Answer:
Option A and B are correct
Step-by-step explanation:
We have to add here
6x+5y=1.
6x-5y=7
sow e will get 12x=8 , x=8/12=2/3
Option A is correct.
If We substract bottom from furst then
6x+5y=1
-6x+5y=-7
10y=-6
y=-6/10=-3/5
we put y=-3/5 in any equation and find x
6x+5(-3/5)=1
6x=4
x=4/6=2/3
So Option B also correct.
