(b)3 Pounds
(c)7 Pounds
Step-by-step explanation:
A clerk in a health food store makes bags of trail mix. The amount of trail mix in each bag is listed below.
(a)What is the combined weight of the 1/2 -lb bags?
(b)What is the combined weight of the 3/4 -lb bags?
(c)What is the total weight of the trail mix used in all the bags?
The amount of Trail Mix is listed below:
1/4lb,1/4lb,3/4lb,1/2lb,1/4lb,3/4lb,
3/4lb,3/4lb,1/2lb,1/4lb,1/2lb,1/2lb
(a)There are 4 bags which weigh [tex]\dfrac{1}{2}lb[/tex]
Therefore:
Their Combined Weight = [tex]4 X \dfrac{1}{2}lb =2 lb[/tex]
(b)There are 4 bags which weigh [tex]\dfrac{3}{4}lb[/tex]
Therefore:
Their Combined Weight = [tex]4 X \dfrac{3}{4}lb =3 lb[/tex]
(c)The total Wight of all the mix is gotten as follows:
Weight of all [tex]\dfrac{1}{4}lb[/tex] bags + Weight of all [tex]\dfrac{1}{2}lb[/tex] bags + Weight of all [tex]\dfrac{3}{4}lb[/tex] bags
Weight of all [tex]\dfrac{1}{2}lb[/tex] bags =[tex]4 X \dfrac{1}{2}lb =2 lb[/tex]
Therefore, using the values derived in (a) and (b)
Total Weight = 2+3+2 =7 lb.
