1. The like graph is dated day by day. To make it easier you could maybe do two days at a time. For example, 24- sep- 26- sep. This will decrease less confusion. To graph it correctly just make the line for the higher numbers taller and for the smaller, shorter.
2. I gave you the answer for this one it the last sentence . :)
Tha last one PR=XY is not true.
It should be PR=XZ.
Six times seven equals forty two
The answer is B,
Explanation: I did the math :)
Y = 500(1 + r)^x; where r is the rate and x is the number of years.
500(1 + r)^2 = 551.25
(1 + r)^2 = 551.25/500 = 1.1025
1 + r = sqrt(1.1025) = 1.05
Therefore, the equation that represents y, the value of the item after x years is
y = 500(1.05)^x
