Answer:

14

Step-by-step explanation:

if b=4 and a=2, then you substitute both those values into the equation, turning (4b - a) into (4*4 - 2), then you use order of operations, meaning you multiply the 4 times the 4, which turns it into 16-2, and then subtract 2 to finally reach your answer of 14.

Jorge’s monthly bill from his Internet service provider was $25. The service provider charges a base rate of $15 per month plus
Hatshy [7]

Answer:

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
