You need to get the x’s by themselves. Subtract the 6 making 4x=2 1/2x +6. Then subtract the 2 1/2x making 1 1/2x=6. Finally you need to do 6/1.5=x. I did 1.5 because it is the same as 1 and 1/2z your answer will be 4.
From F.S 1, consider this series : 8, 1, 8, 8, 64, 64*8.
Again, consider the series 2, 1/4, 1/2, 1/8, 1/16, 1/(8*16). Clearly, the difference of the 6th and the 3rd term is different for them. Insufficient.
<span>From F.S 2, let the series be </span><span><span>a,b,ab,a<span>b2</span>,<span>a2</span><span>b3</span>,<span>a3</span><span>b5</span></span><span>a,b,ab,a<span>b2</span>,<span>a2</span><span>b3</span>,<span>a3</span><span>b5</span></span></span><span>.

Answer:
50 cups of coffee
Step-by-step explanation:
So what you do is take 3.50 then subtract 1.50 to get the profit of one cup of coffee. ($2) Then you do the $100 and divide it by the $2 and find out how many cups of coffee he has to sell to get to the $100. (50)
