Jorge’s monthly bill from his internet service provider was $25. the service provider charges a base rate of $15 per month plus $1 for each hour that the service is used. find the number of hours that jorge was charged for that month. a. 25 hours b. 20 hours c. 10 hours d. 15 hours

Jorge was charged for 10 hours that month

Step-by-step explanation:

  Given : Jorge’s monthly bill from his Internet service provider was $25.

Also given :  The service provider charges a base rate of $15 per month plus $1 for each hour that the service is used

We have to find the number of hours that Jorge was charged for that month.

Let the number of hour be x,

Total bill =  base rate + 1 (number of hours used)

Total bill =  base rate + 1(x)

Substitute the values, we get,

⇒ 25 = 15 + 1 (x)

Solving we get,

⇒ 25 - 15 = x

10 = x

Thus, Jorge was charged for 10 hours that month

Option C is correct!

Step-by-step explanation:

Let x be the number of hours used by Jorge.

for 1 hour the cost = $1

for x hours the cost will be = 1(x ) = x

Base rate = $15

so total monthly payment = Base rate + hour payment

                                            = 15 +x

 total monthly payment = 25

therefore

            15+x  = 25

                x = 10

Jorge was charged for 10 hours in that month.

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

a² + b²= c²

24² + 7² = c²

c= 25
