In this question, Adrian initially has $52,000 and his salary is 1.2 times the previous year's salary. This means the income should look like this:52000*1.2^n
30% of his income is budgeted for rent, then the equation should look like this: 30% * income= 30%*(52000*1.2^n)
Adrian's income increases by $2,300 each year as a result of gifts will make this equation:2300n
if you put the 3 equation together you will get
f(n)= 52000*1.2^n - 0.3(52000*1.2^n) +2300n
f(n)= 36400*1.2^n +2300n
Answer:D

<span>PAPER MONEY.
As wealth increases, owning a large number of gold and silver coins becomes a security problem. As coins are portable, they are also easy to steal. The next step in the development of money was for people to leave their surplus gold and silver coins with a goldsmith who had a reputation for honesty and who operated premises which were secure. The goldsmith would give a receipt, which would entitle the owner to withdraw their coins when they needed them. This was the beginning of paper money.</span>

Answer:
38.9
Step-by-step explanation:
Lets say, first number = x
Second number = 3x+7
Total = 49
(x)+(3x+7)= 49
4x+7 = 49
4x = 42
x = 42/4
x= 10.5
x= 10.5
3x+7 = 3(10.5)+7 = 38.9
Hope this helps!!
