Answers for sheet # 210
1) $19.49 + $24.02 = $43.51; they do not have enough
$53.21 - $43.51 = $9.70 still needed
2) 20-(6 * 3) + (3 * 20) – (2 * 20) – 5 + 6 = 23
3) 28.50 – 1.50 = 27 spent on movies
27/3 = $9 each on the movies
1.50/3 = $.50 each on the candy
4) $177.25 - $48 = $129.25 left
Bob will have $129.25 of his money left
5) (400 – 5 + 15)/5 = X
(395 + 15)/5 = X
410/5 = 82; There will be 82 teams of 5 people each.
