If there were only sandwiches bought, there would be 15, if there were only salads bought there would be 20. There’s probably more than one possibility, but that’s the best I can do, considering how long it’s been since I’ve done this type of problem. I’m all the way to learning determinants, so I really have to think to remember these. Sorry in advance if this doesn’t help at all, I’m not the best at this, but I can still try.
Answer:
Step-by-step explanation:
To find (c.g)(x) we basically use the function d(x) as your variable, x, and plug it into c(x). So we replace every x in c(x) with the function d(x), 
c(g(x))=4(x^{2} +5x)-2
c(g(x))4
+20x-2

Answer:
APY = 0.04 or 4%
Step-by-step explanation:
Given the annual percentage rate of 3.5% that is compounded quarterly, and a principal of $6,500:
We can use the following formula to solve for the annual percentage yield (APY):
where <em>r</em> = interest rate = 3.5% or 0.035
<em> n</em> = number of compounding periods per year = 4
We can plug in the values into the equation:
APY = 1.03546 - 1
APY = 0.04 or 4%
1.5, 2.25, 3.375, 5.0625, 7.59375... and so on
