Barry had 𝟓𝟎 doubles last season which is 𝟏𝟎 more than his best season. Willy had 8 more
doubles than Derek last season. Willy had the same number of as Barry’s best season. Let 𝑏
represent the number of doubles Barry had during his best season, 𝑑 represent the number of
Derek’s doubles last season, and 𝑤 represent the number of Willy’s doubles last season . How
many doubles did Derek have last season?
Solution:
Barry
50
b 10
Willy
b
d 8
Derek
d
Let’s Start with Barry
b + 10 = 50
b + 10 – 10 = 50 – 10
b = 40
Now we can solve Willy’s tape diagram
b = d + 8
40 = d + 8
40 – 8 = d + 8 – 8
32 = d
Derek had 32 doubles

1. The PE teachers are organizing supplies for this year’s field day. In order to have enough
materials for all of the students, they need twice as many hula hoops as Frisbees. The number
of flags required is ten times more than the number of hula hoops. The number of cones that is
needed is half as many flags. If they have a total of 396 supplies, how many cones do they
have?
ANSWER:
Flags Cones Frisbees Hula hoops total
20 10 1 2 33
240 120 12 24 396
They will have a total of 120 cones.
Let f represent the number of Frisbees. Therefore, 2f represents the number of hula hoops, and
20frepresents the number of flags and 10f represents the number of cones.
f + 2f + 10f + 20 f = 396
33f = 396
33f ÷ 33 = 396 ÷ 33
f = 12
Therefore, the PE teachers have 120 cones because 10(12)=120
