Question

A student works at a job in order to save money to buy a desktop computer. The student works 80 hours each month. The desktop computer costs $850. Part A The student plans to work for 5 hours each day, but only on days when scheduled to work. The function f(d)=80−5d represents the number of hours of work remaining for the month after working for d days. Which statement is true?

Answer 1

The function f(d)=80−5d represents the number of hours of work remaining for the month after working for d days

Explanation:

Suppose the student works for 6 days 5 hours then the number of hours left for the month will be given by

f(d)=80−5d where d is the number of days.

f(6)= 80- 30= 50

50 hours will be left after working for 6 day 5hours

The function f(d)=80−5d represents the number of hours of work remaining for the month after working for d days.

Now suppose the student works for 10 days 5 hours then the number of hours left for the month will be again given by

f(d)=80−5d where d is the number of days.

f(10)= 80- 50= 30

30 hours will be left after working for 10 days 5hours
