Step-by-step explanation:
Answer:
s=6 years
m=48 years
Step-by-step explanation:
Let
Mother's age=m
Son's age=s
m=8*s
m=8s (1)
m+6=9/2(s+6)
m+6=9/2s+27 (2)
Substitute (1) into (2)
m+6=9/2(s)+27
8s+6=9/2s+27
8s+6-9/2s-27=0
8s-9/2s-21=0
(16-9/2)s-21=0
7/2s=21
s=21÷7/2
=21×2/7
=42/7
s=6
Present age of the son=6
m=8s
=8(6)
m=48
Present age of the mother=48
The Original price of the meal was $12.16.
Discount Percent is defined as the discount given on the product per hundred .
For Example . if there is 10% discount on a price of $100.
The final amount will be $90.
Final amount paid by Fiona = $8.25
percentage discount = 10%
Let the original amount be x.
According to the question ;
x - 10% of x = 8.25
Since Fiona also had a discount coupon of $3.
The original amount will be $9.16+$3=$12.16.
Therefore , The original price of the meal was $12.16.
