To complete this, #5 =
2 shirts and 3 ties, and $20 shirts and $15 ties.
Shirts total = $40, 15/100 * 40 = $6 saved.
Ties total = $45, 1/10 *45= $4.50
6 +4.50 = 10.50.
The ans = A

1: D
2: A
4/5 = 8/10, while 1/2 = 5/10
Therefore, (8 - 5)/10 = 3/10
3: B
3, 13, 23, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 43. Total = 14
4: C
116/4, as they must be equally split into four classes.
5: A
Discounts are: 0.15 x 20 = $3 (for shirts), 0.10 x 15 = $1.5 (for ties)
Therefore, 3 x 2 + 1.5 x 3 = 6 + 4.5 = $10.50 discount.
6: A
2n would make it an even number, regardless, meaning 2n + 1 or 2n 1 would make it an odd number. n - 2 would also make an odd number.
7: N/A
8: D
Answer should be new/old, 9/5. This gets an answer of 180%, so 80% increase.
To check it over, $5 x 180% = $9.
9: D
Dividing both top and bottom of the fraction by 3 to get 14/3.
10: N/A
