Answer:
$150
Explanation:
Total money to raise = $500
Marty = 1/3 of $500
= 1/3 × 500
= 500 / 3
= $166.67
Hope = 1/6 of $500
= 1/6 × 500
= 500 / 6
= $83.33
Natasha = 20% of $500
= 20 / 100 × 500
= $100
Available amount = Marty + Hope + Natasha
= $166.67 + $83.33 + $100
= $350
how much money does stanley need to raise
=Total needed - available amount
= $500 - $350
= $150
Stanley needs to raise $150
