Answer:
Dividing by a fraction is multiplying by the reciprocal
15.09/1/100=15.09*100=1509
267.4/1/10=267.4*10=2674
Answer:
Semi-annually: A = $24 178.51
Quarterly: A = $24 205.73
Monthly: A = $24 224.13
Step-by-step explanation:
The formula for compound interest is
A = P(1 + r)ⁿ
A. Compounded semi-annually
Data:
P = $20 000
APR = 4.8 %
t = 4 yr
Calculations:
n = 4 × 2 = 8
r = 0.048/2 = 0.024
A = 20 000(1+ 0.024)⁸
= 20 000 × 1.024⁸
= 20 000 × 1.208 926
= $24 178.51
B. Compounded Quarterly
n = 4 × 4 = 16
r = 0.048/4 = 0.012
A = 20 000(1+ 0.012)¹⁶
= 20 000 × 1.012¹⁶
= 20 000 × 1.210 286
= $24 205.73
C. Compounded monthly
n = 4 × 12 = 48
r = 0.048/12 = 0.004
A = 20 000(1+ 0.004)⁴⁸
= 20 000 × 1.004⁴⁸
= 20 000 × 1.211 207
= $24 224.13
Even bc it doesn’t go through the origin
Answer:
1. 14%
2. 98%
3. 52%
4. 13%
5. 39%
6. 28%
7. 20%
8. 37%
9. 17%
10. 19%
Step-by-step explanation:
To get a percentage divide the small number by the big number and then multiply by 100.
1. 28/200 = 0.14 * 100 = 14
2. 931/950 = 0.98 * 100 = 98
3. 364/700 = 0.52 * 100 = 52
4. 13/100 = 0.13 * 100 = 13
5. 273/700 = 0.39 * 100 = 39
6. 161/575 = 0.28 *100 = 28
7. 200/1000 = 0.2 * 100 = 20
8. 68/400 = 0.37 * 100 = 37
9. 68/400 = 0.17 * 100 = 17
10. 95/500 = 0.19 * 100 = 19
Answer: $335
Step-by-step explanation: 4*-60=-240. $-240 is the profit for the next 4 months. Add this to 450. 450+(-240)= 450-240=210. Next add the final month's profit. 210+125= 335.
