A seesaw spinner designed for children aged 6–8 years old has 4 seats. The total weight limit for 4 riders is 170 pounds. Four children want to use the seesaw spinner. Three of the four children already weigh a total of 120 pounds. At most, how heavy can the fourth child weigh for the total weight to be within the limit? Write the missing operation and symbol so the inequality will represent the maximum weight of the fourth player.(1 point)

Stefani needs to earn at least $250, and she already earns $48 from babysitting.
Let x represent the additional amount she needs to earn.
The inequality to represent this situation is:
48 + x ≥ 250
To solve for x, we need to isolate x by subtracting 48 from both sides:
x ≥ 250 - 48
x ≥ 202
Therefore, Stefani needs to earn at least $202 more.
