a.

b=cost per burrioto

t=cost per taco


b.

3 burritos and 4 tacos costs 11.33; 3b+4t=11.33

9 burritos and 4 tacos costs 22.07; 9b+4t=22.07


c. solve

3b+4t=11.33

9b+4t=22.07

mulitply irst equation by -1 and add to 2nd to cancel t's


-3b-4t=-11.33

<u>9b+4t=22.07 +</u>

6b+0t=10.74


6b=10.74

divide both sides by 6

b=1.79

subsitute back


3b+4t=11.33

3(1.79)+4t=11.33

5.37+4t=11.33

4t=5.96

divide both sides by 4

t=1.49


solution: 1 taco costs $1.49 and 1 burrito costs $1.79

How much will a one time investment of $1000 be when invested at 6% for 40 years and compounded annually. Round your answer to t
Vanyuwa [196]

The one time investment of $1000 would worth $10285.72  after 40 years at 6% rate of return

What is annual compounding?

Annual compounding means that the number of times interest is compounded annually is once, compared to semiannual compounding where the interest on the investment is calculated twice a year.

The worth of the investment after 40 years means its future value after having invested $1000 for 40 years using the below formula for future value of a single cash flow:

FV=PV*(1+r)^N

FV=future worth of investment=unknown

PV=initial investment=$1000

r=rate of return=6%

N=number of years of investment=40

FV=$1000*(1+6%)^40

FV=$1000*1.06^40

FV=$1000* 10.2857179371259

FV=$10285.72
