Fred spent half his allowance on going to the movies he then washed the family car for six dollars he now has eleven dollars how
kotykmax [81]

Answer:

He gets $10 for his weekly allowance.

Step-by-step explanation:

Let x represent the amount that Fred gets for his allowance weekly.

Fred spent half his allowance on the movies. This means that the total amount that he spent on the movies is x/2. The amount that he is left with would be

x - x/2 = x/2

He washed the family car for six dollars. This means that the total amount that he is left with would be

x/2 + 6

if he now has eleven dollars, it means that

x/2 + 6 = 11

x/2 = 11 - 6 = 5

x = 2 × 5 = $10
