There are several different ways to approach a math problem and arrive at
the correct answer. The solutions provided here are believed to be the most basic
approach.
Remember:
To change a fraction to a decimal, divide the numerator by the denominator
Examples:
½ = 1 ÷ 2 = .5
¼ = 1 ÷ 4 = .25
To change a percentage to a
decimal, move the decimal two places to the left
Examples:
50% = .50 95% = .95
3% = .03
To change a decimal to a
percentage, move the decimal two places to the right Examples:
.5 = 50% .25 = 25%
1.50 = 150% |
1. 6,500 ÷ 12 = 541.67
541.67 x 5.5 = $2,979.19
2. 1,712 ÷ 90 = 19.02
19.02 x 19 = $361.38
3. 405,000 x 3.5% = 14,175 (Down payment)
405,000 x 96.5% = 390,825 (Loan amount)
390,825 x 1.5% = 5,862.38 (Points)
$14,175 (down payment) + $5,862.38 (Points) = $20,037.38
4. 319,000 x 5% = 15,950 (Gross commission)
15,950 ÷ 2 = 7,975 (50% of gross commission)
7,975 x 30% = 2,392.50 (Broker's share of listing side)
7,975 x 50% = 3,987.50 (Broker's share of selling side)
2,392.50 + 3987.50 = $6,380
5. 100% - 4.5% (broker's commission) = 95.5% (Sellers required share)
280,000 (seller's required net) ÷ 95.5% = $293,193.71
6. 325,000 ÷ 1,000 = 325
325 x $6.00 = $1,950
7. 216,000 x 6.25% = 13,500 (Annual interest)
13,500 ÷ 12 = $1,125 (1 month interest)
8. 369,000 X 63% = 232,470 (Assessed value)
232,470 ÷ 100 = 2,324.7 (Units of 100)
2,324.7 x 3.81 = 8,857.11 (Annual taxes)
8,857.11 ÷ 360 = 24.60 (Daily tax rate)
24.60 x 19 days = $467.40
9. 525,000 ÷ 2,750 = $190.91
10. 100% + 12% = 112%
630,000 ÷ 112% = 562,500
562,500 ÷ 112% = 502,232.14
502,232.14 ÷ 112% = 448,421.55
448,421.55 ÷ 112% = 400,376.38
11. 125 x 70 = 8,750 x 4 floors = 35,000 sq. ft.
35,000 - 1,200 (Unusable space) = 33,800 (Rentable space)
20.75 x 33,800 = 701,350 (Annual rent)
701,350 ÷ 12 = $58,445.83 (Monthly rent)
12. 25 acres x 24% = 6 Acres, open space
19 acres ÷ .5 = 38 Lots
38 lots x 175,000 = $6,650,000
Option B $6,650,000
Option A -5,000,000
$1,650,000
