Question

Jim is paid 10$ per hour at his job.he currently has $1,000 in his bank account .in order to go on a trip with his friends he needs to have $2,000.how many hours over the next few weeks must he work until he reaches the amount needed to go on the trip?if one of the three given dollar amounts change,how would the change the number of hours that him must work?

Answer 1

Linear Equation:
2000 = 10h + 1000
-1000            -1000
1000/10 = 10h/10
100 = h
It will take Jim 100 hrs to make the $1000 he needs to pay for the trip.

Cost of trip: If you raise the cost, then Jim will have to work more than 100 hrs; if you lower the cost, he will have to work less than 100 hrs.
Hourly wage: Raising Jim's wage, will allow him to work less than 100 hrs; lowering his wage, will force Jim to work more than 100 hrs.
Current Balance: If you add money to Jim's current balance, it will decrease the amount of money he has to acquire, allowing him to work less than 100 hrs. If you were take money from Jim's current deposit, it will increase the amount of money Jim has to acquire, allowing him to work less than 100 hrs.
