Question

The table shows the amount of recycling collected by three teams, rounded to the nearest pound, in each of three categories.

Team Glass Plastic Paper

1 18 3 8

2 10 9 14

3 7 12 5


(a) What percent of the plastic collected by all the teams did Team 2 collect?

(b) What percent of Team 1's collection was glass?

(c) Make a multiple bar graph to represent the amount collected by the teams in each of the three categories.

(d) Create a stacked bar graph to represent the amount collected by the teams in each of the three categories.

Answer 1

(a) 37.5%

(b) 62.069%

Explanation:

Team Glass Plastic Paper Total

1 18 3 8 29

2 10 9 14 33

3 7 12 5 24

Total 35 24 27 86

(a)

Amount of plastic collected by all the teams=24

Plastic collected by Team 2=9

Hence, percent plastic collected by Team 2 with respect to all the teams=

`(9)/(24)*100\\ \\=37.5\%`

Hence, Team 2 has 37.5% plastic as compared to the plastic among all the teams.

(b)

total collection by team 1=29

collection of glass by team 1 =18

Hence, percent collection of glass by team 1 is given by:

`(18)/(29)*100\\ \\=62.069\%`

(c)

The multiple bar graph to represent the amount collected by the teams in each of the three categories is attached to the answer.

(d)

The stacked bar graph is attached to the answer.
