Answer:
Jenny´s age is 19 and her mother is 43.
Step-by-step explanation:
1. Plug in the first value of the set
41 is different from 62, so Jenny isn´t 12 years old.
2. Plug in the second value of the set
50 is different from 62, so Jenny isn´t 15 years old.
3. Plug in the third value of the set
59 is different from 62, so Jenny isn´t 18 years old.
4. Plug in the fourth value of the set
Therefore Jenny´s 19 years old.
5. Calculate Jenny´s mother age:
As the sum of their ages is 62 ages, we have the following equation

Answer:
<em>The total percentage discount was 19%</em>
Step-by-step explanation:
<u>Percentages</u>
Suppose the original price of the shirt was x.
A discount of 10% reduces the price by:
10*x/100 = 0.1x
Thus, the discounted price is:
x - 0.1x = 0.9x
The second discount reduces the price by:
10*0.9x/100 = 0.09x
The new discounted price is:
0.9x - 0.09x = 0.81x
With respect to the original price, the last discounted price has been discounted by:
x - 0.81x = 0.19x
This means the total percentage discount was 0.19*100 = 19%.
The total percentage discount was 19%
