Answer:
C. 60%
Step-by-step explanation:
<u>Consider 1st row of table</u>
Total Price = P= 22.50
Discount=D=13.50
Percent discount=(D/P) x 100
=(13.5/22.5) x 100
= 60%
<u>Consider 2nd row of table</u>
Total Price = P= 27
Discount=D=16.20
Percent discount=(D/P) x 100
=(16.2/27) x 100
= 60%
Now we know discount rate is r=60%
Hey there!
The first thing we can do is find the number of third in 4.
We can do this by multiplying 4 by 3 since there are 3 thirds in a whole.
4 x 3 = 12
So, 4 = 12/3
If she studies for 2/3 an hour each night, then we can divide 12 by 2 to figure out how many 2/3 go into 12/3.
12 ÷ 2 = 6
So, she studied for 6 days.
Hope this helps!
