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)
_____
<em>Check</em>
$600 + 75 + 750 + 75 + 1500 = $3000 . . . as it should

Well, if any number is higher than '5' it turns one number more. So, here's a good rhyme to help you: "Five or more, up the score, Four or less, let it rest." The maximum number it could be would have to be '444' because it is not bigger than 445, which would turn to 500.
Answer:
K=24
Step-by-step explanation:
Add 60 on both sides
10k=240
Now divide 10 on both sides
240/10=24
10/10k=k
k=24
28/32 reduces to 7/8
42/48 reduces to 7/8
equivalent fractions are proportionate....so yes, they are proportionate
