Answer:
- Total cost: $3000
- Martha: $600
- Emily: $75
- Alexandra: $750
- Laura: $75
- Lisa: $1500
Step-by-step explanation:
The percentages add to 95%, so the dollar amounts (total $150) comprise 5% of the cost. Then the total cost is ...
total cost × 5% = $150
total cost = $150/0.05 = $3000
And the percentages are ...
20% × $3000 = $600 (Martha's share)
25% × $3000 = $750 (Alexandra's share)
50% × $3000 = $1500 (Lisa's share)

$600 + 75 + 750 + 75 + 1500 = $3000 . . . as it should
