Question

Kathy is a repair technician for a phone company. Each week, she receives a batch of phones that need repairs. The number of phones that she has left to fix at the end of each day can be estimated with the equation P = 108 − 23d, where P is the number of phones left and d is the number of days she has worked that week. What is the meaning of the value 108 in this equation

Answer 1

Answer

Kathy starts each week with 108 phones to fix

Step-step explanation

P=108−23d

Here, P is the number of phones left to be fixed yet and d is the number of days worked.

Since 23 is multiplied by d,23 denotes the mobile phones fixed every day and since 23d is subtracted from 108 to give the remaining phones yet to be fixed, 108 must denote the total number of available phones.

Thus, Kathy starts each week with 108 phone to fix.
