Find the amount that is in the account if $4500 is compounded daily at 3.25% for 6 years
Sindrei [870]

Step-by-step explanation:

1st year interest calculated = 3.25/100 × $4500/1 = $146.25

2nd year principal = 1st year principal + 1st year interest = $4500 + $146.25 = $4646.25. 2nd year interest calculated = 3.25/100 ×$4646.25/1 =$151

3rd year principal = 2nd principal + 2nd year interest = $4646.25 + $151 = $4797.25. 3rd year interest calculated = 3.25/100 × $4797.25/1 = $155.91

4th year principal = 3rd year principal + 3rd year interest =$4797.25 + $155.91 =$4953.16. 4th year principal calculated = 3.25/100 × 4953.16/1 =$160.98

5th year principal = 4th year principal + 4 year interest = &4953.16 +$160.98 = $5114.14. 5th year interest calculated = 3.25/100 × 5114.14/1 =$166.21

6th year principal =5th year principal + 5th year interest = $5114.14 + $166.21 =$5280.35. 6th year interest calculated = 3.25/100 × 5280.35/1 =$171.61

Amount = main principal + compound interest =$4500 +&146.25 +$151+$155.91+$160.98+$166.21+$171.61 =$5451.96

Identify the equation that does not belong with the other three. Explain your reasoning. 5x = 20, 4b = 7, 8w = 32, 12y = 48
liubo4ka [24]

Answer:

4b = 7

Step-by-step explanation:

5x = 20 has solution x = 4

8w = 32 has solution w = 4

12y = 48 has solution y = 4

whereas 4b = 7 has solution b = \frac{7}{4}

The other 3 equations have a solution of 4 making 4b = 7 the odd one out
