The answer to each question is in parentheses at the beginning of each solution.
1)
($2.40)
Albert must have half the money. Half of $4.80 is $2.40.
2)
(26)
7 ª 5 = (7 × 5) - (7 + 7 - 5) = 35 - 9 = 26.
3)
(6)
Product = 9 × 1 × 2 = 18. Sum = 9 + 1 + 2 = 12. 18 - 12 = 6.
4)
(a or
20th)
Every 3rd picture is on the far right. The middle picture must be one less than a
multiple of 3. Twenty is one less than 21.
5)
(36 or
36¢)
Since 2B + 3P = $1.46, then, 4B + 6P = $2.92. Since 4B + 2P = $1.48, 4P = $2.92 $1.48 = $1.44. Then, 1 pear = $1.44 ÷ 4 = $.36.
6)
($41)
There is a total of $180. The 2nd and 3rd stacks contain $90 and the 4th and 5th stacks
contain $58. $90 + $58 = $148 in stacks 2, 3, 4 and 5. That leaves $180 - $148 =
$32 in the 1st stack. Since the 1st and 2nd stacks contain a total of $73, the 2nd stack
contains $73 - $32 = $41.
