kate has $30. she earns $20 and spends $48. she earns $20 more and spends $18. how many dollars does kate finally have

Answer 1

$4

Explanation:

30+20=50

50-48=2

2+20+=22

22-18=4

if she has 30 then gets 20 she has 50. Then she spends 48 dollars leaving her with only 2 dollars. She then makes another 20 dollars so she now has 22 dollars. She spends 18 dollars leaving her with 4 dollars.
