Answer:
28
Step-by-step explanation: add all sides together
Answer:
the first answer is correct
the second answer is correct if they messed up on the question and meant to ask for the MAD of set B
I think the 3rd answer is incorrect (I got 1.09), so you might want to double-check your 3rd answer since it is asking for "times bigger", not how much bigger, which means how many times larger is the MAD of set A than that of set B and to find how many times bigger a number is than another number, you have to divide the first number by the second number.
Step-by-step explanation:
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
Multiply 120 times .7 because you just Turn the percent into a decimal
