If self father is thinking of buying his son a six-month movie pass for $40. with pass, matinees cost $1.00. if matinees are nomally $3.50 each each, how many times must 13th attend in order for it to benefit his father to but the pass?

He must attend 17 times  to benefit his father to buy the pass.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

So, we have to write an equation for the price with pass and another equation for the price with no pass. Assuming that the number of matinees is x.

If we equal the costs:  

40+ 1 x = 3.50 x

40 =3.50x -1x

40= 2.50x

40/2.50 =x

16=x

if he attends 16 times the cost will be the same for both cases.

He must attend 17 times to benefit his father to buy the pass.

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
