1). Total cost for a rental = $12 just to talk to them + $8 per hour .
$44 = 12 + 8 (number of hours)
32 = 8 (number of hours. ____________________
2). 333 = 6 x (number of students on each bus) + 9 mores students
324 = 6 x (number of students on each bus) . ______________________________
3). If all 3 numbers were the same number, then each one would be 1/3 of 138. That's 46 .
Take 1 away from one of the 46s and add it on to another 46 . Their sum is still 138, but now you have 3 consecutive numbers. ________________________________
4). $150 = cost of 6 books + $12 left over.
$138 = cost of 6 books. _________________________________
5). If all three numbers were the same number, then each of them would be 1/3 of 84. That's 28.
Take 2 away from one of the 28s, and add it onto another one. Their sum is still 84, but now you have 3 consecutive even numbers. _________________________________
6). Keith has 45 cards today. This morning, before his dog ate any of them, he had 90. That was after he bought 6 new ones. ___________________________________
7). Sandy has 14 comic books. Before she bought 6 new ones, she had 8 . That's the half she had left after she sold half of them. ___________________________________
8). Sally has $11 now. Before she earned $9 washing the car, she had $20 . That's the half she had left after she spent half at the movies. ____________________________________
9). Fred spent $31 for a soft drink and 7 candy bars. $3 of that was for the drink, so the 7 candy bars cost $28 . _____________________________________
10). If all three numbers were the same number, then each one would be 1/3 of 105. That's 35 .
Take 2 away from one of the 35s and add it onto another one.
They still all add up to 105, but now you have three consecutive odd numbers.
