Answer:
No, she is $10 short.
Explanation:
Cash inflow= $1800 + $250=$2050
Cash outflow=$800+$250+$150+$250+$60+$40=$1550
20% of cash inflow = $510 ($2050*0.2)
$2050-$1550=$500
She could do an extra hour of babysitting or cut her groceries by $10 (lots more possible examples these are just a couple).
