Answer:
28.58 pounds, about 29 pounds
Step-by-step explanation:
Poultry meat with bones ; divide number to be served by 2.5
Meat with little or no bone ; divide number to be served by 3.5
If number of guests to be served = 100
Meat served = 100
The number of pounds of chicken required :
Number of guests to be served / meat served
Hence,
100 / 3.5
= 28.58 ; which is about 29 pounds
3 divided by 5 equals 0.6
Given:
Total amount of Mingfa and her sister = $130
If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.
To find:
How much money does Mingfa actually have?
Solution:
Let, Mingfa have $x and her sister has $y initially. Then,
...(i)
If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.
...(ii)
Substitute the value of x from (ii) in (i).
Divide both sides by 4.
Putting
in (i), we get



Therefore, Mingfa have $95.
The answer to the problem are -3 and -8 because the two equation are being solved for 0
