REMEMBER: Area of Triangle ½ x B x H
How many triangles are there? Are the
triangles the same size or different sizes?
Triangle BFC  ½ x 8cm x 15cm  60cm2
Triangle DFC  ½ x 8cm x 15cm  60cm2
Triangle AFB  ½ x 6cm x 8cm  24cm2
Triangle AFD  ½ x 6cm x 8cm  24cm2

How many packs of gum will put Kelly’s total at $100 or more? _____
The difference of $82.11 & $80.44
Clothes only: $96.60 x 0.85 (15% discount) = $82.11
Clothes + Gum: $96.60 + ($0.79 x 5 packs gum) = $100.55
$100.55 x 0.80 (20% discount) = $80.44
 Kelly actually saved money by spending more before the discount.

GOAL: Find a value for Games 6 and 7, that will keep the average number
of points at 12, the median number 14, but will have range greater than 10.
 Games 1 through 5 ONLY
 Mean (average) (14+6+10+16+14) divided by 5
 Mean (average) = 12
 Median (order numbers least to greatest) 6, 10, 14, 14, 16
 Median = 14
 Range (difference of largest and smallest number in set) 16 - 6  Range = 10
