Answer:
41%
Step-by-step explanation:
1200-850=350
350 is the markup, now we need the percentage
the orginal price was 850 so we just need to divide 350 by 850
we get 0.4117...
convert that to a percentage and we have 41% markup
Answer: E = 56
Step-by-step explanation:
E is proportional to √C
To remove proportionality, introduce a constant (k).
E = k × √C
From question,
E = 40 and C = 25
So,
40 = k ×√25
40 = k × 5
k = 8
Now,
C = 49
k = 8
E = ?
E = k√C
E = 8 × √49
E = 8 × 7
E = 56
Answer: $12 an hour
Step-by-step explanation:
Rosey works 37 hours a week and 4 weeks in a month.
Total hours are:
= 37 * 4
= 148 hours
In order to at least cover the $1,776 in expenses she incurs every month, Rosey's hourly pay must be:
= expenses / working hours in month
= 1,776 / 148
= $12 an hour
