Four children.cost $5per month plus a 15$ sign-up fee.If she received a bill for $120, for how many months did she purse subscriptionsfor her children

Question

She has 4 children to give the x box live subscription you need to find out how many months she purchased for her children

Answer 1

Hi Jack,

 

Let's begin by assigning a letter to represent our unknown:

    x = number of subscription months

 

Now let's write an equation to represent the breakdown of her bill (monthly cost + sign-up fee):

    5x + 15 = 120 (equation)

 

Solving for our unknown (x):

    5x = 120 - 15

    5x = 105

     x  = 21 (number of subscription months)

 

We can verify our answer by plugging it back into our equation to check that both sides match:

    5(21) + 15 = 120

    105 + 15 = 120

    120 = 120 (both sides match)

 

Since both sides match, we are confident that our answer is correct.

 

Thanks for submitting this problem and glad to help.
