When Serena is 10, her mom is 3*10=30. Her mom is 20 years older than Serena.
If her mom's age divided by half is equal to Serena's, then she will be twice as old as Serena.
20 + 20 = 40
20 * 2 = 40
Serena will be 20, her mom will be 40.

Answer:The amount of commission made is 144
Step-by-step explanation:
The department store worker gets paid 325.00 per week plus 4% commission of their total sales. This means that the worker's earning is not fixed. It varies with the amount of sales made
if the worker sells 3600 of the merchandise, it means that the worker's sales commission will be 4% of 3600 of the merchandise
Sales commission earned by the store worker = 4/100 × 3600
= 0.04 × 3600 = 144
Set each of the binomials equal to zero and solve for x. The two values will be the zeros of the equation:
(x-4) = 0 (x+11) = 0
x-4 = 0 x + 11 = 0
x = 4 x = -11
The zeros of the equation are -11 and 4
