1.
Let w be the number of weeks it takes for Konrad to have more than $72.
The equation we can derive is 57 + 3w > 72.
Then solve:
57 + 3w > 72
3w > 15
w > 5
Then w must be 6, which is the next number greater than 5.
2.
Let w be the number of weeks it takes Omar to have enough money for the car.
The equation we can derive is 1800 + 35w [tex]\geq[/tex] 2150.
Then solve:
1800 + 35w [tex]\geq[/tex] 2150
35w [tex]\geq[/tex] 350
w [tex]\geq[/tex] 10
Then w must be 10.
1: (72-57)/3=5
