6/1/6 Review of Integers
1.) Use the number line to solve -5 + 3 = (-2)
-1 0-2-3-4-5 1 2 3 4 5
2.) Use zero pairs to solve 4 + -3 = 1
3.) Use the Addition Rules to solve (-16) + (-5) =(-21) Sum of two negative integers is negative

6/1/6 Review of Integers
1.)
Ben had borrowed $300 from each of his four friends last year. He now has $600 to return back. Find out how much can he return to each of his friends and how much total loan is still remaining.
Total money borrowed 4 x $300 = $1200
He has $600 which he has to return to 4 friends
so each friend gets $600 / 4 = $150
Money left to return to each $300 - $150 = $150
Total Loan still remaining $150 x 4= $600

2.)Five friends plan to buy a gift for their games Instructor. They contribute $35 each. The giftcosts them $150.Find out how much money doeseach one spends
Total money collected $35 x 5 = $175The gift costs them $150 so the total money leftIs $175 - $150 = $25
This needs to be distributed amongst all fiveSo $25 / 5 = $5 Hence each friend spends
35 – 5= $30

3.)
Sarah went for a drive with her father. On the onward journey they sped at a average speed of 60 miles per hour. After 5 hours they turned back And as it was uphill this time they drove at an average speed of 50 miles an hour. Find out how Much would it take them to get home?
