Rue needs to save at least $150 to buy his friend a gift. Rue has $60 now and can save $10 a week for bold italic x weeks. What inequality and graph shows the number of weeks Rue needs to save?
The inequality is 60 plus 10 x greater or equal than 150.
The inequality is 60 plus 10 x less or equal than 150.
The inequality is 60 plus 10 x greater or equal than 150.
The inequality is 60 plus 10 x less or equal than 150.
The correct inequality is: 60 + 10x ≥ 150
This inequality shows that Rue needs to save at least $150 for the gift.
Graphically, this can be represented as a line with a slope of 10/1 (10 dollars saved per week) starting at the point (0,60) on the y-axis. The line crosses at y = 150 around x = 9 weeks, so Rue needs to save for at least 9 weeks to reach his goal.
