Carlos is hoping to save at least $200 in the next four weeks. His mom gives him $30, and he earns money each Saturday morning at his grandmother’s store.

x+

≥

, where x
is the amount Carlos earns each Saturday morning. Carlos must earn at least $
each Saturday morning to have at least $200 in four weeks.

Answer 1

30 + 4x ≥ 200, where x is the amount Carlos earns each Saturday morning.
Solving: 4x ≥ 170, so x ≥ 42.50.
Carlos must earn at least $42.50 each Saturday morning (any amount ≥ $42.50 works).
