$H - 2 = 2 * (B -2)$

Required

H and B

We have:

$H - 2 = 2 * (B -2)$

Open bracket

$H -2 =2B - 4$

Add 2 to both sides

$H -2+2 =2B - 4+2$

$H =2B -2$

Substitute $H = B + 7$

$B + 7 =2B -2$

Collect like terms

$2B - B =7+2$

$B = 9$

Substitute $B = 9$ in $H = B + 7$

$H = B + 7$

$H = 9 + 7$

$H = 16$

Howard’s uncle gave him $885 for his tenth birthday. The money was invested in a savings account with interest compounded at 12%

Stella [2.4K]

Principal Amount = P = $885
Amount Accumulated = A = $3500
Interest rate = r = 12% = 0.12
Compounding period in a year = n = 2
Time in years = t = ?

The formula for compounding is:

$A=P(1+ \frac{r}{n})^{t*n}$

Using the values, we get:

$3500=885(1+ \frac{0.12}{2})^{2*t} \\ \\ 
 \frac{3500}{885} =(1.06)^{2t} \\ \\ 
log(\frac{3500}{885})=log((1.06)^{2t}) \\ \\ 
log(\frac{3500}{885})=2tlog(1.06) \\ \\ 
t= \frac{log(\frac{3500}{885})}{2log(1.06)} \\ \\ \\ 
t=11.80$

This means, it will take him 11.8 or approximately 12 years
