Answer:
1. c. 2601.2
2. b. $3213.45
3. d. $3278.78
Explanation:
1. Simple Interest = Principal * Interest * Term
Simple Interest = $1400*0.066*13
Simple Interest = $1,201.2
Amount after 13 years = $1,400 + $1,201.2
Amount after 13 years = $2,601.2
2. Amount after 13 years = P(1+r)^n
= $1,400*(1+0.066)^13
= $1,400*(1.066)^13
= $1,400*2.29532222032
= $3213.451108448
= $3213.45
3. Amount after 13 years = P(1+r/n)^n*t
= $1,400*(1+0.066/4)^13*4
= $1,400*(1+0.0165)^52
= $1,400*(1.0165)^52
= $1,400*2.34198395106
= $3278.777531484
= $3278.78
