Question

What is the combined weight of the 1/2 lb bags of trail mix?

Answer 1

(a)2 Pounds

(b)3 Pounds

(c)7 Pounds

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
`(1)/(2)lb`

Therefore:

Their Combined Weight =
`4 X (1)/(2)lb =2 lb`

(b)There are 4 bags which weigh
`(3)/(4)lb`

Therefore:

Their Combined Weight =
`4 X (3)/(4)lb =3 lb`

(c)The total Wight of all the mix is gotten as follows:

Weight of all
`(1)/(4)lb` bags + Weight of all
`(1)/(2)lb` bags + Weight of all
`(3)/(4)lb` bags

Weight of all
`(1)/(2)lb` bags =
`4 X (1)/(2)lb =2 lb`

Therefore, using the values derived in (a) and (b)

Total Weight = 2+3+2 =7 lb.
