2. It costs Edgar $2.65 one way to ride the bus to work. He uses the bus to go to and from work four days per week. He buys a bottle of water that costs $1.45 on his way to work each day. How much does it cost Edgar to ride the bus and buy water for one week?
2.65 x 2 (since he has to go both to and from work each day) = $5.30 Add the daily cost of the water bottle (1.45) to make his total cost for one day, which is 6.75 Multiply this number by 4 (because he goes 4 days a week) to get $27 for one week.
