(11+21)-(3-101)=(11+21-3-10=(11-3)+(21-101=8-18=53
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%
The answer is c F(x)= x2-5 and g(x)=c+4
