Answers for sheet # 211
1) 11 x 3 x 1.75 = $57.75 for party favors
12 x 2.75 = $33 for movie tickets
$33 + $57.75 = $90.75 for the party expenses
2) 32 ¸ 8 = 4 people per row
4 people per row x 12 rows = 48 people seated to watch the show
3) Old basketballs = 15; New basketballs = n;
Sum = 133
15 + n = 133
15 – 15 + n = 133 – 15
n = 118
118 new basketballs appeared in his garage.
4) $300 - $160 = $140 still needed
$140 ¸ $20 per week = 7 weeks
Sammy needs to save 7 weeks of allowance to buy the Play Station 2.
5) 96 people x 2 wheels per bike x 24 spokes per wheel = 4608 spokes needed
4608 x. 50 = $2304 spent on spokes
